I was diagnosed with PMR this past February and have been on Prednisone since. Just weened down to 2mg per day in the morning. We live in an area close to the mountains and the weather can change from snow to warmth in a matter of hours. This definately affects my PMR. The pain is so bad that I can hardly get up and walk, let alone do stairs. It's worse in the mornings til about noon. I was diagnosed with Costochondritis many years ago and this week I had some very severe chest pains that I almost went to the hospital. I read up on this website and I saw that others have had the same problem. I went to my doctor the next day and he confirmed that PMR can affect this. I've never had the pain that I've experienced in the past few months. I don't know if I'll ever get off taking Prednisone.
I glad I found this group that can relate to what I'm going thru. It will take over a year before I can see a rheumatologist as they are so back logged here. One very interesting fact I discovered about PMR is that it is prevalent in people from the Scandinavian countries.
