I had a knee scope 5.5 weeks ago and the past two weeks one of the incision holes has small hard lump and it's a little sore when I rub it. The knee almost seems to catch on the lump when I cycle and sometimes walk. I feel I would be walking normal if this wasn't the case. I am not able to get into my surgeon until middle of next week. I feel like it might be scar tissue accumulating, but not sure. Two weeks after the surgery I started doing cross frictional massage on the scars daily for at least 5 minutes and sometimes I rub my massage tool over it. How can I get rid of this?
