Hey guys, I have knee pain whenever I run or do any type of squatting (even body weight). I didn't used to have this till after I had been running a lot to get in shape. I used to be able to run occasionally without any pain. I was wondering if anyone knows what is causing this pain or how I can lessen it or fix it. I really don't want to go to a doctor right now because i just finished a long session of physical therapy for another leg problem. Thanks
