Yes I apparently pulled my hamstring. I just woke up one night about 2 weeks ago to some painful leg cramps and thought taking ibuprofen would be helpful but it was very painful to sit in the car and drive. I went to the Dr. on Monday and started Therapy only 2 days out of the week for the past 2 weeks. I can feel the knots in my right leg but they have moved to the outer right side of my right leg. I feel the knots and so does the therapist. Some people keep telling me it could be my sciatic nerve. I felt the pain in the back below my right butt check in the middle back of my thigh, behind my right knee and in my right calf. I used a rice bag heated in the microwave which helped considerably but like I said it moved to the outter part of my right leg and I tried running a ball over the knot and that is rather painful. Any helpful hints as I ever so slowly heal?
