The inside of my calf and the inside of my thigh are very sensitive to the touch and gets stiff when sitting for a period of time. Once I start to exercise or walk it feels better. I have had this happen to my other leg also in the past. It just started to be sensitive all of a sudden. It does show some redness where the pain is. I do exercise a lot and play racquetball daily. Over time the pain does go away.
