Recently I've been having terrible pain that comes out of no where. I've tried looking it up on google but nothing seems to fit. When it comes, it's a few inches below my belly button, extending down into vagina. It's not a burning feeling like it's more of an ache or stabbing orpulling pain. It's gotten so bad at times that I can't walk or stand up straight, no position makes it go away except then not being straight. I feel better when I sit. I feel pressure and pain when I need to tinkle, and while I am, and after. Sometimes before the pain in the center starts, I feel what kind of feels like cramps on the left side... it kind of migrates down.after a while I feel comfortable without any pain. I really hope some of this makes sence to someone. I'm 20 years old, and have no insurance yet. I am hoping someone else out there knows what this is.
