Hang in there! I've had both knees replaced (not at the same time). It does take time to recover but for me, it has been so worth it!! I, too, did the synvisc injections, cortisone injections but when it was time I knew it. I know it can be overwhelming but many of us have been there.
I'm recovering from a wrist joint replacement/reconstruction right now so it seems my joints just keep deteriorating. Just know my thoughts and prayers are with you. Please let me know if I can answer any questions. I'll be more than happy to try to help you with anything! Take care!
