about 9 days ago i was skateboarding and landed on my nuts on the rail. about 15 minutes later i felt like i was going to throw up. went home laid down and didnt move. i swelled up only on the right side and was very bruised. as the days went on it got better. the bruising went away but my right nut is still large. about 2x as big. it doesnt hurt to walk or anything today but still my nut is big? what should i do?
