I was laying down on a couch. My friend pushed by off, and I rolled over and hit my perineum on the corner of a table that is pretty sharp. It felt excruciatingly painful at first. The skin did not rip, it just aches. I took some Advil and it feels better about 90 minutes later, but I'm not sure if I did any internal damage. Do you think might have done any damage and should I see a doctor?
