@sharenb I have no medical training or background but my first occurrence of PMR took me a little over 3 years before I was able to taper off of prednisone which was started at a 20 mg dosage. The second occurrence of PMR six years later took me about 1-1/2 years before I was able to taper off and the PMR went into remission. I've never heard of an occurrence of PMR that only lasted a few months (not to say that it couldn't happen). I have no experience with injections given to treat PMR. Can you tell me what injection was given to help the PMR?
Have you discussed the symptoms of your husband's difficulty going from sitting to standing with his doctor? When my PMR was active and I was in pain, it was difficult for me to go from sitting to standing and I also had to be careful sitting down.
