Does anyone know of a resource where I can find what taking an overdose of steroids causes "medically" long term? I'm speaking of steroids like prednisone. Any help on this topic would be helpful. I need information to help me with my health long term and what to expect. I was given 100 mg's. over a 10 month period daily plus injections. Now I'm having serious problems. I'd like to know what I'm facing. I have had or have thyroid disease, cushions disease, a vascular necrosis, diabetes, pitutary tumor, and I'm getting a little scared.
