So make an extremely drawn out story short. I've experienced left ankle pain for roughly four months now. Swelling, severe difficulty walking, heat. Xrays normal. Ultrasound for DVT normal. After low dose prednisone helped but didn't heal it, an MRI was done to rule out infury. Well, it turns out I had completely torn a ligament, but what it also showed was that I had a large bone infarct on my tibia. Apparently this is far more common in the hip and knee and eventually leads to a complete replacement of the joint. Several factors scare me- one, that I'm only one year into my diagnosis of lupus and that prednisone saved my life last year after I was going into kidney failure, two, that I'm only 29 and that this is a long road ahead of bone degeneration and fair amount of pain, and three who knows where else it may have occurred since they've only done that one MRI and four, I'm assuming (maybe incorrectly) they will probably have to do some kind of surgery I'm just not sure what.
I know osteonecrosis is fairly uncommon, but does anyone have any experience or knowledge on this subject? Any insight would be most appreciated!
