Hi I am a little fearful of blood clots in the leg...I pulledmy groin several weeks ago and it has remained tender and a couple days ago it really hurt and was hard and swollen (the extreme upper inside of thigh). Then next day ok just tender again. Today I had my friend do a bowen treatment on me. Right now I feel a little achy and am running a fever of 100.1. I was wondering what are signs of blood clots. Leg is fine to walk on and can do most things, it's not swollen twice its size or anything. Just tender in the groin. I wonder if the bowen treatment released some toxins and now I have to go thru a fever to get rid of them.
