Hi, I have been c/o pain in my left knee front, back and outer aspect for past year. I went for physio at the request of my G.P. for treatment but since this I am much worse especially at night. Area above knee very uncomfortable and persistent pain along the upper part of the shaft of the femur bone again at night.During the day my leg although slightly uncomfortable, does not affect me like it does at night.Take difene 100mg before I go to bed, but to no avail. I m female, 53 and weight appropiate for my height.
