Broke my knee yesterday and tore a ligament playing football. The ligament actually ripped off a chunk of bone when it came off and i'm going to get arthriscopic surgery. Plus im in this annoying "knee imobilizer" that supposed to keep my knee straight. 4 weeks till i get surgery and its literally impossible for me to get into the shower without me agravating my knee bad. Medic u got any tips besides pain killers to make the pain go away?
