I am a reasonably healthy 72 year old, a retired Physicist/Engineer and before the PMR used to cycle and swim daily. I live with my wife in a house built in 1880 and we are improving it year by year.
PMR probably started May 2023 with ache / pain in top of left inner thigh and sometimes right thigh. It did not feel like a problem with a joint but also the muscular pain was a deep ache not like other muscle pains I have had.
In May I was swimming 20 - 30 lengths 5 times per week but had to occasionally stop swimming for a couple of weeks. The pain would ease but come back when I begun swimming - eventually I had to stop swimming. But the problem did not go away it steadily got worse and even walking was becoming painful with a dull ache in thigh and calf on both legs.
By October 2023 I was struggling with walking even 20 mins without pausing from the discomfort and by mid November I could not even get on my bicycle, I found it very painful to tie my shoe laces and even to put on a shirt in the morning was a struggle. It had to change.
During November & December 23 I saw a couple of GP's and was sent for x-rays on my hips/pelvic area and they showed my joints were in good condition with little deterioration. The diagnosis was then PMR and this was confirmed by the initial dosage of Prednisolone which stopped the real pain in my shoulders and legs. Starting to take Prednisolone at 15mg/day and within 3 days the real pain in shoulders and legs has gone. I could lift my arm above my shoulders and put on a shirt with no pain and tie why shoe laces with no pain. The stiffness and muscle ache remained but not real pain.
Since then I've reduced the Prednisolone twice from 15 to 12.5mg/day and when reaching 10mg things started to change for the worse. On the 12.5mg/day I could walk quite well (5km’s per day) and I started swimming again. The problem is only in legs, mostly thighs but also calves. No issue at all with my shoulders. When I got to 10mg/day muscle ache increased and the after the first reduction to 10mg I had to revert to using a walking stick which I have been using even in the second period of 15mg/day. I am on 10mg for the next 2 weeks and that finishes with a blood test and then GP visit. I do not see what can be next other than going back to 15mg/day. Note blood tests have shown no increased inflammation for the last 6 months.
