<s>[INST] Hello.  I had a microdisectomy 8.5 weeks ago.  L4/5 and L1/S1.  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? [/INST] If i understand correctly you are reffering 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 refering to what we call sacroiliac joint disfunction , 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 jogging exercise  multiple times a day you will be fineGood Luck </s>
