I thought I was developing bursitis because of hip pain and limited mobility. However, after a few days, it changed. Unlike anything I ever felt before, I stared to fall and caught myself - pain! I then realized I couldn't sit or stand without help. A couple days over the weekend then I dropped a line to my doctor. He immediately prescribed steroids. It seems to be localized in my right SI Joint. And it seems that My SI joint has become on fire and yet makes walking and my pelvis weaker. I don't trust walking at all. I keep losing my leg out from under me. What a lousy event. I wonder how long it'll last?
