A.S. is such an erratic condition that is is difficult to tell if your current problems are just the A.S. finding a new way to torment you. It is all too easy for us and the doctors we see to just blame everything on our A.S. The symptoms you describe are much the same as some I have myself experienced over the years. I am glad that you have seen a doctor about it. At least now you know it is not anything serious. The chances are that given time it will get better but just how much time I can't tell. Three months is not all that long to wait for a muscle injury to improve.
