Jakatak, you are the first person I ever heard of that talks of outer thigh pain. I have it all the time, if I try to walk it gets worse and worse, tighter and tighter with every step until it is almost impossible to walk anywhere anymore. I have had sacroiliac pain off and on for years. Tried looking up thigh pain with no answer yet. Does it hurt your thighs to walk? Both of mine do the same thing but one does it far more than the other. Right now I am having lots of pain trying to sleep due to the lower back pain and all the butt pain. OUGH! Tried icing and think it is better than heat. Just wish I could find a doc that could give me some insight so am going to ask my ortho about it. If only I thought I could get help for it I would be so glad. Froggie
