I have 2 areas of indentation in the muscle (one on each thigh). I noticed the one on my left thigh a few months ago and showed it to my primary dr. He said not to worry about it unless it gave me problems. Well, now I have another one just like it on my right thigh alittle higher up. It doesn't hurt/sting feel any different than the rest of my leg. (My dr was stumped as to what it might be). I wasn't concerned until the second appeared in the last couple of weeks. Now it has me wondering. I know in horses (which I raise) we call these sweeney's (it's caused from them leaning on the shoulder muscle and killing the nerve ending thus causing the indentation) but I can't find anything on the web about similar conditions in people. I know I haven't been leaning on the fence or stall door so that's not it
any ideas???

Hmmm, interesting. Excellent question, Horsemommy.

I have indentations, like the ones you have on your thighs, only mine are located on my gluteus maximus (bum areas) and I've wondered if mine are related to neuromuscular disease that I have (that affects my ischial tuberosity).

In the past, I had asked the question online. I don't remember the insights others offered (where I posted had crashed and the posts/responses are gone).

I may have written it down someplace. I'll look over the next couple of days. If I can find notes on it, I'll let you know what people stated.

My husband has one of those indentations on his thigh. He does not have any neurological disease but when he was sixteen he had a severe cycle accident and was in hospital with leg traction for a broken leg (in those days).
Looks like the muscle is dead in that one spot - so yes my guess is that it would be to do with nerves or muscles dying.
