Hi sir. I am 25 years old female. Recently I did abdominal strengthening exercise like straight like raising, and fully flex knee till chest in supine position. Last week I played with my child and while twisting my leg I heard a click sound, no pain or swelling initially. But I heard a click sound whenever I walk from that day, Gradually I couldn't squat or climb stairs, tightening of knee and vague pain started. Which was relieved on full knee extension. For past three days I have swelling above patella that is above knee joint. But. Till now no sever pain. Putting ice pack and taking pain killer because pain is sever when I squat. But I could walk, lift weight etc. But since I am scared I am just resting in full extension. Please help me what might be the problem. Any menisceal tear like that?
