I was out to dinner last night with some friends, and noticed that my left knee was sore. I noticed a soft lump
under my skin, on my top of my knee cap
. It is about the size of a gum ball, maybe a little bigger.
About three weeks ago, I fell on cement onto my knee and got all cut up. It healed just fine, but I am wondering if that has something to do with my lump.
Should I go see a doctor?
