Polymyalgia Rheumatica (PMR)

Polymyalgia rheumatica (PMR) is an inflammatory condition that primarily causes pain, aching, and stiffness in the shoulders, neck, and hips. Symptoms are typically worse in the morning or after periods of inactivity, and morning stiffness can last for an hour or longer. Fatigue, reduced energy, and a general feeling of being unwell are also common.

Causes of Polymyalgia Rheumatica

The exact cause of polymyalgia rheumatica is not fully understood. However, it is believed to involve an abnormal immune system response that triggers inflammation in the body.

Some theories suggest that environmental factors, such as viral infections, may contribute to triggering the condition in individuals who are genetically predisposed to developing it. However, no specific infectious cause has been established.

Duration and Prognosis

The course of polymyalgia rheumatica can vary considerably from person to person. In some individuals, the condition gradually resolves over several months to a couple of years. In others, symptoms may persist for several years, requiring longer-term treatment and medical monitoring.

Although PMR can sometimes resolve over time, symptoms may return during or after treatment, a process known as a relapse or flare.

Most people respond well to treatment, particularly corticosteroids such as prednisone, which can significantly reduce inflammation, pain, and stiffness.

Risk Factors and Associated Conditions

Polymyalgia rheumatica (PMR) primarily affects adults over the age of 50, with the risk of developing the condition increasing as people get older. Women are also more likely to develop PMR than men.

Association with Giant Cell Arteritis (GCA)

Polymyalgia rheumatica can occur alongside another inflammatory condition called giant cell arteritis (GCA), also known as temporal arteritis. GCA causes inflammation of the blood vessels, particularly the arteries in the head and around the temples.

Approximately 15 out of every 100 people with polymyalgia rheumatica also develop giant cell arteritis.

Giant cell arteritis is a serious condition because inflammation can reduce blood flow to the optic nerve and lead to permanent vision loss if left untreated.

Symptoms may include:

• New or persistent headaches, particularly around the temples.
• Scalp tenderness.
• Jaw pain or fatigue when chewing.
• Blurred or double vision.
• Sudden loss of vision.

Anyone with PMR who develops new headaches, jaw pain when chewing, or visual disturbances should seek urgent medical assessment. Sudden vision changes or vision loss require emergency medical attention.

Polymyalgia rheumatica (PMR) is best diagnosed by a physician who is familiar with the condition, often a rheumatologist, a medical specialist who focuses on arthritis, inflammatory conditions, and autoimmune diseases.

Because several other medical conditions can produce symptoms similar to PMR, a careful and thorough assessment is essential to establish the correct diagnosis and rule out other possible causes.

Conditions that may resemble polymyalgia rheumatica include rheumatoid arthritis, certain types of cancer, infections such as endocarditis (infection of the inner lining of the heart), and thyroid disorders. These conditions can cause symptoms such as fatigue, muscle pain, and stiffness around the shoulders and hips.

Medical History and Physical Examination

The diagnostic process typically begins with a detailed medical history. PMR may be suspected in individuals over the age of 50 who experience pain and stiffness around the shoulders and hips, particularly when symptoms are worse in the morning or after periods of inactivity. Persistent fatigue and difficulty performing everyday activities are also important symptoms to consider.

The physician will then perform a comprehensive physical examination to assess areas of pain, stiffness, and restricted movement. The examination also helps identify signs that may suggest another underlying condition.

Blood Tests and Imaging

Additional investigations are often recommended to support the diagnosis and exclude other medical conditions.

Blood Tests for Polymyalgia Rheumatica

Blood tests play an important role in evaluating polymyalgia rheumatica (PMR). They help identify inflammation in the body and rule out other medical conditions that may cause similar symptoms.

Tests for Inflammation

Polymyalgia rheumatica is an inflammatory condition, so blood tests often show elevated markers of inflammation. However, some individuals with PMR may have normal inflammatory markers.

Common blood tests used to assess inflammation include:

• Complete Blood Count (CBC): Measures the levels of different blood cells and may identify abnormalities such as anemia, which can occur with chronic inflammation.
• Erythrocyte Sedimentation Rate (ESR): Measures how quickly red blood cells settle in a test tube. An elevated ESR may indicate inflammation in the body.
• C-Reactive Protein (CRP): Measures the level of a protein produced by the liver in response to inflammation. Elevated CRP levels can indicate an active inflammatory process.

Tests to Rule Out Other Diseases

Because several medical conditions can produce symptoms similar to polymyalgia rheumatica, additional blood tests may be ordered to help distinguish PMR from other inflammatory, autoimmune, and metabolic conditions.

These tests may include:

• Rheumatoid Factor (RF): Helps assess the possibility of rheumatoid arthritis, which can sometimes cause symptoms similar to PMR.
• Antinuclear Antibodies (ANA): Helps identify certain autoimmune conditions, including lupus and other connective tissue diseases.
• Thyroid-Stimulating Hormone (TSH): Evaluates thyroid function, as an underactive thyroid can cause muscle aches, stiffness, and fatigue.
• Creatine Kinase (CK): Measures an enzyme found primarily in muscle tissue. Elevated levels may indicate muscle injury or inflammation and can help distinguish PMR from certain muscle disorders.

Together, these blood tests help physicians evaluate inflammation, investigate alternative diagnoses, and build a clearer picture of the patient’s overall health.

It is important to remember that no individual blood test can confirm or exclude polymyalgia rheumatica. Results must be interpreted alongside the patient’s symptoms, physical examination, and other clinical findings.

Treatment of polymyalgia rheumatica (PMR) typically involves medications to control inflammation, along with physical therapy and exercise to maintain mobility and restore normal movement in the shoulders and hips.

With appropriate treatment and ongoing medical care, most people experience significant improvement in their symptoms and can return to their usual daily activities.

Early treatment is important to reduce inflammation, relieve pain and stiffness, and preserve the range of motion in the affected joints. When pain and stiffness remain untreated, individuals may begin avoiding certain movements and activities. Over time, reduced mobility and prolonged inactivity can lead to muscle weakness, physical deconditioning, and joint contractures, which involve a permanent shortening of muscles or surrounding soft tissues that restricts movement.

Physical Therapy and Exercise for Polymyalgia Rheumatica

Physical therapy and appropriate exercise play an important role in managing polymyalgia rheumatica. Gentle movement and targeted exercises can help improve pain, reduce stiffness, maintain flexibility, and restore mobility in the shoulders and hips.

Exercise also helps strengthen the muscles surrounding the affected joints, improve physical function, and reduce the effects of prolonged inactivity.

Regular physical activity may also help manage fatigue, improve sleep, and support emotional well-being.

A physiotherapist experienced in treating arthritis and inflammatory conditions can develop an individualized exercise program based on the patient’s symptoms, mobility, and physical abilities. The program may include gentle stretching, range-of-motion exercises, and gradual strengthening activities.

Exercises should be performed regularly, with intensity adjusted according to symptoms and recovery. During periods of significant inflammation, overly strenuous activity should be avoided.

Medications for Polymyalgia Rheumatica

Corticosteroids (Prednisone)

Prednisone is the main medication used to treat polymyalgia rheumatica. It is a corticosteroid that works by suppressing the immune system’s inflammatory response, helping to reduce pain, stiffness, and inflammation.

Many people experience noticeable improvement within a few days of starting treatment, and some may feel significantly better within the first 24 to 48 hours.

Once symptoms are adequately controlled, the prednisone dose is gradually reduced through a process known as tapering. Treatment often continues for a year or longer, depending on the patient’s response and whether symptoms return during dose reduction.

Reducing prednisone too quickly or stopping it prematurely can cause symptoms to flare up again. For this reason, dosage changes should always be guided by a physician.

Some patients experience recurring inflammation or difficulty reducing their prednisone dose. In these situations, a rheumatologist may consider additional medications, such as methotrexate or other steroid-sparing treatments, to help control the disease while reducing long-term corticosteroid exposure.

Long-term prednisone use can cause side effects, including weight gain, elevated blood pressure, increased blood sugar, osteoporosis, and a higher risk of infection.

Because of the risk of bone loss, patients taking prednisone for an extended period should discuss calcium and vitamin D intake, bone density monitoring, and whether additional osteoporosis-prevention medication is appropriate.

Patients should always discuss the potential benefits and risks of prednisone treatment with their physician.

Non-Steroidal Anti-Inflammatory Drugs (NSAIDs)

Non-steroidal anti-inflammatory drugs (NSAIDs) are medications that help reduce inflammation and relieve pain.

Although NSAIDs can help manage musculoskeletal discomfort, they are generally not effective enough to control the underlying inflammation of polymyalgia rheumatica and are not recommended as a replacement for corticosteroids during initial treatment.

In selected cases, a physician may recommend an NSAID to help manage additional joint or musculoskeletal pain. However, combining NSAIDs with prednisone can increase the risk of gastrointestinal complications, including stomach ulcers and bleeding.

Long-term NSAID use can also increase the risk of kidney problems, elevated blood pressure, and cardiovascular complications. Their use should therefore be discussed with a healthcare professional.

Analgesics (Pain-Relieving Medications)

Analgesics are medications used to relieve pain. Unlike corticosteroids, they do not directly control the inflammation responsible for polymyalgia rheumatica or prevent disease-related complications.

Common pain-relieving medications include:

• Acetaminophen (paracetamol): May help relieve mild to moderate pain.
• Opioid medications: Such as morphine, which may be prescribed in selected circumstances for severe pain but are generally avoided for routine PMR management because of their potential for dependence and other adverse effects.

Analgesics may sometimes be used alongside other treatments to improve comfort while the underlying inflammation is being addressed.

Disease-Modifying Antirheumatic Drugs (DMARDs)

Disease-modifying antirheumatic drugs (DMARDs) are medications commonly used to treat inflammatory conditions such as rheumatoid arthritis. Certain DMARDs may also be beneficial for people with polymyalgia rheumatica, particularly those who experience repeated relapses or require prolonged corticosteroid treatment.

Methotrexate is sometimes prescribed alongside prednisone to help control inflammation and reduce the amount of corticosteroid needed over time. This can help minimize the potential side effects associated with long-term prednisone use.

Other medications may be considered in selected circumstances. However, hydroxychloroquine (Plaquenil) is not an established treatment for polymyalgia rheumatica.

For individuals who experience repeated relapses or cannot adequately reduce their prednisone dose, newer treatments targeting specific inflammatory pathways, such as sarilumab, may also be considered by a rheumatologist.

The choice of additional medication depends on the patient’s symptoms, medical history, treatment response, and risk of medication-related side effects.

Long-Term Management and Monitoring

Successful management of polymyalgia rheumatica involves more than simply controlling pain and stiffness. Regular medical follow-up is important to monitor inflammation, assess treatment effectiveness, and identify potential medication side effects.

Because PMR can relapse, patients should report any return of shoulder or hip pain, morning stiffness, or fatigue to their physician.

The overall goal of treatment is to achieve sustained control of inflammation, minimize corticosteroid exposure, preserve mobility, and help patients maintain their independence and quality of life.

The exact cause of Diffuse Idiopathic Skeletal Hyperostosis (DISH) remains unknown.

The condition involves abnormal bone formation, in which bone-building cells called osteoblasts deposit calcium and form new bone in areas where it would not normally develop, particularly along ligaments and at tendon attachment sites. However, the precise reasons for this abnormal calcification and bone growth are not yet fully understood.

The roles of genetics and environmental factors in the development of DISH also remain unclear. Although uncommon, the condition can occur in multiple members of the same family, suggesting that genetic factors may contribute to its development.

Ankylosing spondylitis (AS) should be diagnosed early and managed effectively to control inflammation, maintain spinal flexibility, and preserve joint mobility. Early treatment can help slow disease progression and reduce the risk of long-term complications, including the fusion of bones in the spine.

Although existing structural damage caused by AS cannot usually be reversed with medication, appropriate treatment can help relieve pain, reduce inflammation, improve mobility, and preserve physical function. Regular follow-up appointments with a rheumatologist are essential, along with completing any recommended blood tests and imaging scans to monitor disease activity and assess treatment effectiveness.

The management of ankylosing spondylitis generally involves two key approaches:

• Physical therapy and exercise: Regular physical activity, physiotherapy, and daily stretching can help reduce stiffness, maintain flexibility, improve posture, and support overall mobility.
• Medication: Medications can help control inflammation, relieve pain, and improve physical function and quality of life.

A summary of the main treatment options available to help manage ankylosing spondylitis and improve patients’ quality of life is provided below.

Conditions That Can Mimic Polymyalgia Rheumatica

Polymyalgia rheumatica (PMR) can sometimes be difficult to distinguish from other inflammatory conditions, particularly rheumatoid arthritis (RA), because both conditions can cause joint pain, stiffness, and inflammation around the shoulders.

Rheumatoid arthritis may initially affect the shoulders and cause symptoms similar to PMR. However, the two conditions differ in their typical patterns of joint involvement. Rheumatoid arthritis commonly affects additional joints over time, particularly the hands, wrists, and feet, whereas polymyalgia rheumatica primarily causes pain and stiffness around the shoulders, neck, and hips. Unlike rheumatoid arthritis, PMR does not typically cause destructive inflammation within the joints themselves.

A number of other medical conditions can also produce symptoms that resemble polymyalgia rheumatica without being forms of arthritis. These include certain cancers, infections such as endocarditis (an infection of the inner lining of the heart), and thyroid disorders.

Other possible causes include inflammatory muscle conditions, medication-related muscle symptoms, and other systemic inflammatory diseases.

Because several conditions can present with symptoms similar to PMR, a thorough medical assessment is important. Doctors may use a combination of medical history, physical examination, blood tests, and additional investigations to establish the correct diagnosis and rule out other underlying conditions.

Early diagnosis and treatment of Polymyalgia Rheumatica Education are essential to help manage the condition and slow its progression.

Appropriate treatment can reduce inflammation, relieve pain and stiffness, maintain mobility, and help prevent long-term complications, including damage to the spine. Effective management may also help reduce the risk of complications associated with chronic inflammation, such as cardiovascular disease, and support overall health and well-being.

There is no specific diet proven to stop Polymyalgia Rheumatica or reverse spinal changes. A Mediterranean-style pattern—vegetables and fruit, whole grains, legumes, nuts, fish, and unsaturated fats—is a reasonable approach for overall health. Foods such as tomatoes and bell peppers can be included, but they shouldn’t be considered treatments for Polymyalgia Rheumatica.

Tomatoes and arthritis

Tomatoes can be a nutritious addition to an Polymyalgia Rheumatica Education -friendly diet, although they do not cure Polymyalgia Rheumatica Education or directly reverse joint damage.

• Lycopene: Tomatoes are particularly rich in lycopene, an antioxidant that helps protect cells from oxidative stress. Cooked tomatoes and tomato products can provide especially well-absorbed lycopene.

• Vitamin C: Supports collagen formation and normal connective-tissue function.

• Antioxidants: Tomatoes contain vitamin C, carotenoids, and other plant compounds that contribute to overall antioxidant intake.

• Potential anti-inflammatory effects: Laboratory and observational research suggests that compounds in tomatoes may influence inflammatory pathways, but evidence that eating tomatoes significantly reduces arthritis pain or inflammation in people is still limited.

• Heart health: Tomatoes can contribute to a heart-healthy diet, which is particularly relevant for people with Osteoarthritis Education because RA is associated with increased cardiovascular risk.

Some people with arthritis report that tomatoes or other nightshade vegetables worsen their symptoms. There isn’t strong scientific evidence that tomatoes generally cause arthritis inflammation or should routinely be avoided. If you consistently notice symptoms after eating a particular food, discussing this pattern with a healthcare professional or dietitian can be more useful than eliminating foods unnecessarily.

For osteoarthritis, tomatoes are best viewed as part of an overall nutritious eating pattern. For Polymyalgia Rheumatica Education, diet can complement medical treatment but shouldn’t replace disease-modifying medication when it is prescribed.
