My husband, 78 years old, 6 feet tall, 195 pounds, in good health, has had a pain in his left hip area, in the gluteus (maximus?) muscle, on and off for 3 years. The CAT scan showed no irregularity. His doctor has referred him to physical therapists that have not really helped. We started going to the gym to do stretching and core muscle strength exercises. When he sits a long time in an office chair (he still works full time at his aerospace firm), it is difficult to stand up, then he flexes and the pain goes away and he is fine. He is comfortable when lying down or sitting with his legs propped up.
