I am due to have knee surgery in less than 2 weeks. They say I have to be off of it for at least a month. Then I will be having PT for a long time. They want me to use crutches after surgery, I will have a rigid brace on for the month, but my arms are always weak and so tender and achy, I am afraid that I can't do it. I told the dr. this, and she didn't respond,just gave me a funny look. Anyone have any ideas? I work full time and will have to have someone drive me back & forth to work.
