I have an 11 year old boy who is starting to go into puberty. He is very active in Tai Jitsu and Judo. Tonight after Tai Jitsu (with lots of kicking tonight), he is complaining of a pressure in his left testicle. He denies getting hurt during practice tonight, has normal urination, and no other pain, nausea, etc. I gave him Tylenol and it has helped a little, but has not relieved it like Tylenol typically does for his aches from workouts or minor injuries. I examined him briefly and see no discoloration, swelling, or abnomality.
