Good luck, Catrin! My knees have been exceedingly cranky lately (moving pissed them off) - so you have my sympathies.

I just wanted to add that I had had knee things resolve, but take much longer than anyone suggested. I too had a fall at work and dealt with Workers' Comp. They wanted to do exploratory surgery, and I declined. Took about 9 more months for the swelling to go down and the pain to go away, but it did (at least until the recent patellar-femoral issues and other stuff on the other knee).
