What a really knowledgeable Chiropractor! I've suffered hip pain for about 6 months. About 60-90 days ago I went to regular MD who said it was piriformis. Dr. Herlehy examined me and determined it to be my pelvis. In the first visit he managed to relieve tightness in my right hamstring and hip. Sent me away with an ice pack and stretching instructions. A GREAT doctor that I highly recommend -- I just wish I had gone to him sooner!!!
