About Polymyalgia Rheumatica
The exact cause of polymyalgia rheumatica is unknown, but it is believed to be an inflammatory disorder that involves inflammation of the joints, tendons, and bursa (fluid-filled sac found near joints).
Non-modifiable risk factors for PMR, which are factors that cannot be controlled to reduce the risk of developing the condition, include:
- Age: PMR typically affects people over the age of 50, and it is more common in individuals over 65.
- Gender: Women are more likely to develop PMR than men.
- Ethnicity: People of Northern European and Scandinavian descent have a higher risk of developing PMR.
- Genetic factors: Some gene variations may increase the risk of developing PMR. However, these genetic links have not been consistent across different populations.
Modifiable risk factors, which are factors that can be controlled to reduce the risk of developing the condition, include:
- Environmental factors: Certain environmental triggers, such as viral infections, may play a role in the development of PMR. However, the specific links have not been established conclusively.
It's important to note that these risk factors do not guarantee the development of PMR, and individuals without these risk factors can still develop the condition. If you have concerns about your risk for PMR, it's best to consult with your healthcare professional for personalized advice.
The most common early symptoms of polymyalgia rheumatica include:
- Pain and stiffness in the shoulders, upper arms, neck, lower back, hips, and thighs
- The pain and stiffness are usually worse in the morning
As PMR progresses or reaches a higher severity, other common symptoms may occur:
- Fatigue
- Low-grade fever
- Joint swelling
- Difficulty walking
- Weight loss
In some cases, PMR can also be associated with giant cell arteritis (GCA), which is characterized by symptoms such as:
- Headaches and scalp tenderness
- Jaw pain, especially when chewing
- Visual problems, including double vision or vision loss
It's important to note that the symptoms of PMR can vary from person to person. If you're experiencing any of these symptoms or have concerns about your health, it's best to consult with a healthcare professional for an accurate diagnosis and appropriate management.
To diagnose polymyalgia rheumatica, healthcare providers commonly perform the following examinations, tests, and procedures:
- Physical exam: The healthcare provider will look for physical signs of PMR, such as joint pain and stiffness, especially in the shoulders, neck, and hips.
- Medical history: The healthcare provider will ask about your medical and family history to gather information about your symptoms and previous diagnoses.
- Lab tests: Specific lab tests may be recommended to check for inflammation and blood abnormalities. These may include:
- Erythrocyte sedimentation rate (ESR) test: Measures inflammation levels in the body. High ESR levels can indicate PMR pr other inflammatory diseases.
- C-reactive protein (CRP) test: Another blood test that detects inflammation. Elevated CRP levels are common in PMR.
- Helps rule out other conditions and check for anemia, which sometimes occurs with PMR.
- Imaging studies: The most common indicator of PMR is the presence of bilateral subdeltoid/subacromial bursitis, which means inflammation of the fluid-filled sacs on both sides of the shoulder. Common imaging tests to evaluate the extent of inflammation and rule out other conditions include:
- Ultrasound: Uses sound waves to create detailed images of soft tissues, helping distinguish PMR from other conditions.
- X-ray: Provides images of bones and joints to assess for any damage or abnormalities.
- Magnetic resonance imaging (MRI): Produces detailed images of the shoulder joints and surrounding tissues, making it effective for identifying bursitis and other inflammation-related changes.
To determine the stage or severity of PMR, additional examinations, tests, and procedures may include:
- Follow-up physical exams: Regular physical exams are important to monitor changes in symptoms and assess disease progression and joint damage.
- Repeat lab tests: Periodic measurements of ESR and CRP levels can help gauge the level of inflammation in the body.
It's important to consult with your healthcare provider for personalized advice regarding examinations, tests, and procedures for diagnosing and monitoring PMR.
The main goals of treatment for polymyalgia rheumatica are to relieve symptoms and improve overall quality of life. Here are the different types of treatments and how they work to achieve these goals:
- Medications:
- Corticosteroids: These anti-inflammatory medications are the go-to for PMR treatment. They help reduce inflammation, relieve pain, and improve stiffness. Doctors usually prescribe low to moderate doses, taken orally, to manage PMR symptoms. The dosage is gradually decreased once symptoms is reduced.
- Disease-modifying antirheumatic drugs (DMARDs): These medications act on inflammation at the cellular level and may be prescribed in combination with corticosteroids, especially for people who experience side effects from corticosteroids or to control flare-ups.
- Therapies:
- Physical therapy: This can help improve strength, flexibility, and range of motion, reducing pain and stiffness associated with PMR.
- Occupational therapy: It focuses on adapting daily activities to reduce strain on affected joints and muscles.
- Self-care and health behavior changes:
- Balanced diet: Eating a balanced diet rich in fruits, vegetables, lean proteins, and whole grains can help manage inflammation. Foods rich in omega-3 fatty acids, like fish, nuts, and seeds, can also help reduce inflammation.
- Regular exercise: Low-impact activities like walking, swimming, or stretching can help maintain joint flexibility, reduce stiffness, and improve overall mobility. Strength training can also support muscle function without overexertion.
- Weight management: Maintaining a healthy weight can reduce strain on muscles and joints, helping to alleviate symptoms.
- Quit smoking: Smoking can worsen inflammation and interfere with the effectiveness of treatments. Quitting smoking can help improve overall health and symptom management.
- Limit alcohol: Reducing alcohol intake can help avoid negative interactions with medications, such as corticosteroids, commonly used in PMR treatment.
- Stress management: Practices like yoga, meditation, or deep breathing exercises can help manage stress, which can indirectly reduce inflammation and pain.
- Proper sleep: Ensuring adequate sleep can help the body heal and cope better with pain and stiffness. Establishing a good sleep routine can support overall recovery.
- Follow-up medical care:
- Monitoring health: Regular blood tests to check for inflammation levels and imaging tests to assess joint damage is important to keep PMR symptoms in check.
- Physical Assessments: Regular check-ups with a healthcare provider can evaluate pain levels, stiffness, and functional abilities. These assessments can guide treatment adjustments
- Additional tests: If symptoms do not improve with medication and lifestyle changes, further tests may be conducted to check for other rheumatic disorders.
It's important to note that medication dosing and treatment plans can vary depending on individual circumstances. Consult with your healthcare professional for personalized advice.
