Hi my name is Dan and I m having a problem with my outer left leg. When I try to sit in a car I get severe pain in my upper outer thigh. I experience the same pain when I try to take a poop as whatever muscle hurts is also being used for that I think. The pain has been there for going on 3 weeks now. I went to med express and they thought it was a high hamstring strain and prescribed prednisone. Prednisone is all gone and although it did help a little with the pain and inflammation my problem is still here.
