Polymyalgia rheumatica (PMR) causes severe muscle pain and stiffness in the shoulders, neck, upper arms, hips, and thighs. It comes on suddenly, often overnight, and makes basic movements - lifting your arms above your head, getting out of bed, climbing stairs - extremely difficult. Despite being relatively common in people over 50, PMR is poorly understood by many PIP assessors.
Which PIP Activities Does PMR Affect?
Dressing and Undressing (Activity 6) - This is often the highest-scoring activity. PMR causes severe shoulder stiffness that prevents lifting arms above the head. Putting on tops, bras, coats, and jackets becomes impossible without help. Pulling clothing over your head requires arm elevation that PMR specifically prevents. If you need someone to help dress your upper body on most days, this scores 2-4 points.
Washing and Bathing (Activity 4) - Cannot reach to wash hair (arms won't lift high enough). Cannot reach behind to wash back. Cannot reach feet to wash them (hip stiffness). Getting in and out of the bath requires core and hip strength that PMR reduces. If you need help, aids, or can't wash certain body parts, this scores.
Preparing Food (Activity 1) - Cannot lift heavy items (pans, plates from high shelves). Shoulder and arm stiffness prevents stirring, chopping, and reaching. Morning stiffness lasting 1-3 hours means cooking breakfast is impossible - and that's the meal you're most likely to prepare alone.
Moving Around (Activity 12) - Hip and thigh involvement limits walking distance. Severe morning stiffness means mobility is worst in the first few hours. Stairs become very difficult. If you hold onto furniture and walls to get around the house, describe it.
Managing Therapy (Activity 3) - Prednisolone (often for 1-2+ years), steroid reduction management, blood tests, rheumatology appointments. Steroid side effects (weight gain, mood changes, osteoporosis risk, insomnia, diabetes) are all PIP-relevant.
Steroid Side Effects Matter
Most people with PMR take prednisolone for 1-2 years minimum. The side effects are significant and affect PIP activities independently: weight gain affecting mobility, insomnia causing fatigue, mood swings affecting social engagement, weakened bones increasing falls risk, raised blood sugar requiring monitoring. Describe every side effect on your form.
The Morning Stiffness Problem
PMR stiffness is typically worst in the morning, lasting 1-3 hours before steroids take effect. During this time you may be unable to get out of bed, dress, wash, or prepare food without help. PIP assessors sometimes dismiss this because "you improve later in the day." But the reliability criteria require you to do things repeatedly - if you can't function for the first 3 hours of every day, you cannot do activities in a reasonable time.
PMR and Giant Cell Arteritis
About 15-20% of people with PMR also develop giant cell arteritis (GCA/temporal arteritis). If you have GCA, this adds headaches, jaw pain, visual disturbance, and the serious risk of permanent blindness. GCA is a medical emergency and should be described separately on your PIP form as an additional condition.
What Evidence Helps?
- Rheumatologist letters
- Blood test results (ESR, CRP showing inflammation)
- Steroid dose history (showing need for ongoing treatment)
- GP records of steroid side effects
- Partner statement describing morning routine and help needed
