I injured my right knee somehow a month ago. Could have been running, playing cricket, or snowboarding... don't know. Anyways, it used to click and get sore a lot initially, but seems to be getting better , with clicking only if I squat all the way down. Doctor didn't find anything cracked in the x-rays, and am going for MRI this week. It's depressing not being able to workout fully, but I am taking it easy, and hoping I don't need surgery lol.
