Hi, i am 23yrs old, height 5 foot 4 inch and weight 44 kg.1 month back,while i was stepping down, the leg was twisted and was getting severe pain then i consulted to a doctor,he gave some medicines. after 2 days i was able to walk properly but again after 5 days it was paining. The doctor told me to use the Knee Brace for 2 weeks, now its not paining but i feel the knee is not stable enough. should i go for MRI scan? Please suggest.
