Hi Dr. Rynne, I drove a long drive a week or so ago, about 1400 miles, now I have muscle soreness going from my hamstring to back of thigh, to glutes to lower back...I am a 34 athletic guy? At first it was my right leg and still is mostly, but when I bend over I feel it aggressively in that leg and some in the left, like I worked out very hard yesterday, but I have been relaxing? Hope it is not a blood clot?
