In about an hour, I have my first physical therapy appointment for my knee. The swelling's gone down, but I still get the popping sound and the PAIN if I move too quickly. I also feel unsteady while walking, and don't know if I need a knee brace or a cane. To top it off, I'm working tomorrow afternoon, so I can't just medicate and forget it. I'm afraid I'm going to leave there in even more pain. Anybody done this before? What are they going to do to me?
