i had pain near my left hip joint about 3 years ago and its still there.there seems no inflammation.all the x-rays were good..when i touch at pelvis area frm outside,the pain is there only.if i press there the pain is unbearable.the doctors found no exact cause of the pain.i m really eager to know what the exact cause is and where the infection is?is there any ways to know about it?..this pain has depressed me for a long time.
