Don’t despair. This is a very painful procedure. I hated the first couple of weeks, everything hurt including my head and back. It felt never-ending. I am eight weeks post OP TKR Right side and just starting to feel like myself. The pain is less, the stiffness remains but that’s normal, PT is painful, but ice and take an OTC before and after and it will be manageable. I know it seems hard to believe but It does get better.
