Post ACL injury knee problems?

R.I.C.E- Rest Ice C Elevate. Be careful when playing sports. I hurt my knee and I really dont do anything anymore and if i do i wrap my knee and put icey hot on. but in your case you should go back to your doctor and talk to him about that. but keep the brace on. I always get popping and cracking in my knee and im gunna be going to the doctor about that. get tested for it.
