Problems contacting the doc

Trying to get physical therapy scheduled, and need to replace my knee brace. I've been calling the doc for 4 days and I finally was able to talk to someone about 30 minutes ago. Tomorrow I'll get a brace replacement and paperwork to get my therapy started. I haven't been taking pain pills now for about 1 1/2days but I might just start. The knee is beginning to bother me, maybe because I've been walking around the house on my leg? Doc says to stay off my leg until I get my new brace.
