Polymyalgia Rheumatica: Causes, Symptoms, and Treatment

What is Polymyalgia Rheumatica?

Polymyalgia rheumatica is an inflammatory condition that primarily affects the muscles and joints, causing significant pain and stiffness. Unlike other forms of arthritis, polymyalgia rheumatica doesn't damage the joints themselves but instead causes inflammation in the tissues surrounding them. This condition typically develops rapidly, with symptoms appearing over days or weeks rather than months.

The hallmark of polymyalgia rheumatica is bilateral muscle pain and stiffness, meaning both sides of the body are affected equally. The polymyalgia rheumatica definition encompasses not just physical symptoms but also the profound impact on quality of life, from disrupted sleep to difficulty performing routine activities, like combing hair or putting on a jacket.

Causes of Polymyalgia Rheumatica

The exact cause of polymyalgia rheumatica remains unclear, though researchers believe it results from a complex interplay of factors. Your immune system appears to mistakenly attack healthy tissues, causing inflammation in the muscles and surrounding areas. Genetic factors play a significant role, with certain HLA gene variations increasing susceptibility to polymyalgia rheumatica.

Environmental triggers may also contribute to developing this condition. Some studies suggest viral infections, like parvovirus B19 or Epstein-Barr virus might trigger polymyalgia rheumatica in genetically predisposed individuals. Seasonal patterns have been observed, with slightly more cases diagnosed during colder months. Recent research also points to changes in the gut microbiome and age-related immune system changes as potential contributing factors.

Symptoms of Polymyalgia Rheumatica

Recognising polymyalgia rheumatica symptoms early can lead to faster diagnosis and treatment. The condition typically develops suddenly, with symptoms appearing over days or weeks:

• Severe morning stiffness lasting more than 45 minutes, according to the NHS.
• Bilateral pain and aching in the shoulders, neck, upper arms, and hip regions.
• Difficulty performing daily activities like raising arms above the head or getting up from a chair.
• Extreme fatigue that doesn't improve with rest.
• Mild fever and general feeling of being unwell.
• Unintentional weight loss and decreased appetite.
• Depression and mood changes.
• Sleep disturbances due to pain and discomfort

Diagnostic Tests and Imaging Techniques for Polymyalgia Rheumatica

Diagnosing polymyalgia rheumatica requires a comprehensive approach, as no single test can definitively confirm the condition. Doctors use a combination of clinical assessment, laboratory tests, and imaging studies:

• Physical examination: Doctors assess muscle tenderness, range of motion, and pain patterns.
• Erythrocyte Sedimentation Rate (ESR) Test: This blood test measures inflammation levels; elevated ESR test results strongly suggest polymyalgia rheumatica.
• CRP Test: Another marker of inflammation that's typically elevated.
• Complete Blood Count (CBC) Test: A complete blood count helps rule out other conditions and check for anaemia.
• Rheumatoid Factor (RF) Test: Usually negative in polymyalgia rheumatica, helping distinguish it from rheumatoid arthritis.
• Ultrasound imaging: Can detect inflammation in shoulder and hip joints, showing characteristic bursitis.
• MRI scans: Provide detailed images of soft tissues and can help detect bursitis or rule out alternative diagnoses.
• PET scan: Sometimes used in complex cases to assess widespread inflammation.
• Temporal artery biopsy: Performed if giant cell arteritis is suspected as a complication.

Who is at Risk for Polymyalgia Rheumatica?

• Age over 50: The condition rarely affects younger adults, with most cases occurring after age 65.
• Female gender: Women are approximately twice as likely to develop polymyalgia rheumatica.
• Genetic predisposition: Having certain HLA gene variants increases risk.
• Family history: Having relatives with polymyalgia rheumatica or autoimmune conditions increases risk.
• Geographic location: Higher rates in northern latitudes suggest environmental factors.

Polymyalgia Rheumatica Treatment Options

Polymyalgia rheumatica treatment focuses on reducing inflammation and managing symptoms effectively. The cornerstone of treatment is corticosteroid therapy, which typically provides considerable relief within 24-72 hours. Your doctor will start with a moderate dose of prednisolone, then gradually taper it over months or years based on your response and symptom control.

Treatment plans are individualised, considering your age, other health conditions, and risk factors for steroid side effects. Regular monitoring through blood tests, including ESR test results, helps guide dose adjustments. Most patients require treatment for 12-24 months, though some may need longer therapy. The goal is finding the lowest effective dose that controls symptoms while minimising side effects. Physical therapy and lifestyle modifications complement medical treatment to maintain mobility and muscle strength.

Medications Used to Treat Polymyalgia Rheumatica

The medication approach for polymyalgia rheumatica focuses on controlling inflammation while minimising long-term risks:

• Prednisolone: The first-line corticosteroid, typically starting at 15-20mg daily.
• Calcium and Vitamin D supplements: Essential for protecting bone health and preventing steroid-induced osteoporosis.
• Methotrexate: Sometimes added as a steroid-sparing agent, especially in relapsing or corticosteroid-dependent cases.
• Proton pump inhibitors: May be prescribed to protect against steroid-related stomach issues.
• Bisphosphonates: For patients at high risk of osteoporosis.

Lifestyle Changes and Home Remedies for Polymyalgia Rheumatica

Managing polymyalgia rheumatica extends beyond medication. These lifestyle modifications can significantly improve outcomes:

• Gentle exercise programme: Start with simple stretches and gradually progress to walking or swimming.
• Anti-inflammatory diet: Include omega-3-rich foods, colourful vegetables, fruits, and whole grains.
• Weight-bearing exercises: Essential for maintaining bone density during steroid treatment.
• Fall prevention strategies: Install grab bars, remove trip hazards, and ensure adequate lighting.
• Stress management techniques: Practice meditation, deep breathing, or gentle yoga.
• Sleep hygiene: Use supportive pillows and maintain a consistent sleep schedule.
• Heat therapy: Warm baths or heating pads can ease morning stiffness.
• Support groups: Connect with others managing polymyalgia rheumatica for emotional support.
• Regular health monitoring: Schedule routine checks for blood pressure, blood sugar, and bone density.

How Long Does Treatment for Polymyalgia Rheumatica Last?

Polymyalgia rheumatica treatment duration varies considerably among patients. Most people require corticosteroid therapy for 12-24 months, though some may need treatment for several years. Your doctor will gradually reduce the medication dose, monitoring for symptom recurrence through regular check-ups and ESR test results.

Tapering too quickly often leads to relapse, requiring dose increases. Factors influencing treatment duration include initial symptom severity, response to therapy, and presence of complications.

Complications of Polymyalgia Rheumatica

Without proper treatment, polymyalgia rheumatica can lead to significant disability and reduced quality of life. The severe pain and stiffness can result in muscle weakness, joint contractures, and loss of independence. Untreated inflammation may persist for months or years, causing chronic pain and depression.

A serious concern is the development of giant cell arteritis in polymyalgia rheumatica patients. This condition affects blood vessels and can cause vision loss, jaw pain, and even stroke if untreated. Warning signs include severe headaches, scalp tenderness, and visual disturbances; seek immediate medical attention if these occur.

Long-term corticosteroid use brings its own risks, including osteoporosis, diabetes, high blood pressure, and increased infection susceptibility. Regular monitoring through blood tests, bone density scans, and blood pressure checks helps prevent or manage these complications.

Living with Polymyalgia Rheumatica

Adapting to life with polymyalgia rheumatica requires both physical and emotional adjustments. Morning stretches after a warm shower can ease stiffness, while planning activities for times when you feel most energetic maximises productivity.

Communication with family and friends is vital. Explain how polymyalgia rheumatica affects you, particularly the invisible symptoms like fatigue. Don't hesitate to ask for help with challenging tasks. Many find that breaking large tasks into smaller, manageable steps prevents overexertion and frustration.

Regular follow-ups with your healthcare team ensure optimal treatment adjustment. Keep a symptom diary noting pain levels, stiffness duration, and medication effects. This information helps your doctor make informed decisions about polymyalgia rheumatica treatment modifications.
