<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hello. I had a microdisectomy 8.5 weeks ago. L45 and L1S1. Very tight in buttock area and tightness in left hamstring. The terrible pain before the surgery is gone. My hips have been hurting very much when sleeping. I have to flip from side to side every hour in order to sleep. The pain is not only in the hip I am laying on but the other one also. Any thoughts?  <response>: If I understand correctly you are referring to a pain behind hip joint assuming it is hip pain hip joint pain comes as a spot pain in front or at the side of hip joint you are referring to what we call sacroiliac joint dysfunction, start walking in place for 5 min pain will improve even go away completely this is normal after being pain free you are regaining normal alignment , do daily jog exercise multiple times a day you will be fine Good Luck
