What now?

Yesterday I kept my appointment with my chiropractor to see what is going on with my knee. That was pretty much a waste of my time.This morning I still have the same problem. I have another appointment Thursday. It would be nice to see some improvement. I am really tired of this doctor passing everything off as age related. Seriously, things don't just stop working over night. There has to be a reason for the pain and I want to know what that is.
