So, I run alot, and this semester I adding lifting weights, and now my left knee is starting to really get messed up. It hurts a good deal after lifting weights, and when I don't move for a long time it freezes up and is hurts to fully extend at first. So I was wondering if any ATOT doctors had a good solution for that? Should I just back off on the lifting/running for a few days, and if I do will it jsut start hurting again when I start back up? I see lots of people with knee or ankle braces, but have never used one, do those help with this sort of problem? Thanks for your help and such.
