My PMR started when I was 70 in 1971. I'd felt a bit stiff and achy for a month but one day I woke up and had trouble turning over in bed, then had to head-butt the light switch because I couldn't lift my hand. My GP diagnosed it from the symptoms and the blood test showed massively raised inflammation markers and I was put on pred right away. Within just a few days I could walk 6 miles. Steroids have that effect. However, my inflammation markers took years to go down to normal and I took my last pred tablet after 6 years. A helpful web site is www.pmrgcauk. Lots of advice from fellow sufferers.
