I know this happened several posts ago, but i'm going to raise it again. I have a a huge problem with the therapists' advice to "keep going through the pain barrier".Go to hospital physio class on a Thursday where we do a curcit class was on the bike not ready to take the peddles round not sure why or how but knee went 3/4 way round I ended up in tears and pain was at a 10 they seem to think it has just strained the knee and keep going through the pain barrier. Now Saturday I have iced the knee elevated rested still in a lot of pain about an 8 don't know what to do for the best. Have booked to see private therapist see if he can help.

That is crazy and is guaranteed to do even more harm to your knee. Don't they know that pain is a warning to stop?
I hope your return to work goes well. Do be prepared to speak up on behalf of your knee and don't do anything to compromise its recovery. Let the owner and the vet lift heavy dogs. Your knees and your back will thank you.
