Sir, I was experiencing pinching on lower side of knee while using stairs as I had lost 12 kgs weight in last month by excessive running. Doctor said I'm having runner's knee. Improvement is there and I'm feeling very less pinch now but i was feeling a little uneasyness in knee and no pain is there so doctor asked me to go for MRI and said that you don't need any kind of surgery and this problem can be dealt with physiotherapy. Please provide me with your consultation as I have to join Indian air force academy on 1st of jan and I'll be going through training for 1.5 years.
