The other day I was working on the roof. Nothing strenuous. While walking up to the top I felt a very sharp pain in my left leg at the front just below my knee. I have had this bruise like patch there for a couple of years now. The pain was right on top of it. My leg was cool to touch. But in that spot it was really warm. Today as I was trying to stand up I had Avery sharp pain in my left testicle.
