Hit vagina on shopping cart, help

Tjay

Sooo a few days ago, me and a friend were being stupid and riding in shopping carts. When we were done and I was getting out, I misinterpreted how far the ground was and I hit myself pretty hard on the bar. It stung and first and bruised extremely quickly on one side. The labia is hard now and itches. I’m not sure what to do, I’ve never had a hard bruise before. I’m 17 and have never gotten a physical and rlly refuse to due to past events.
