I’m in my 8 momth and it still very stiff and when I’m sitting it does not hurt but when I get up to walk it starts hurting after 10 minutes. I had 3 shots of nerve block from my pain management but it still hurts I guess it did not work.S what can that be? I go to physical therapy and do some exercise in the pool that should help a little.I do walk a lot .(help)
