Last year while exercising my left knee got over stretched. I started feeling pIn in standing or sitting in any position. After around three months I consulted a doctor and was told that mi ligament was weak. He prescribed tendocare and one more tablet which provided some relief but I still am not able to sit with folded legs. I am doing gym also n do the leg extension exercise to strengthen my knee but in vain.. Please sugget what should I do. Due to may vague office timings I am not able to visit my doctor.
