Pelvic pain!!

Asia
I'm having real bad pelvic pain lately. It feels like a zing in that area, not so much of a stabbing pain but enough to make me keel over. My mother has a history of ovarian cysts and she just had a hysterectomy for endometriosis. I'm afraid I'm going down the same road and I'm only 23 with no children yet. I've had 2 ultrasounds from my obgyn and they said everything looked normal, I'm thinking of getting a second opinion from another doctor next week. Just looking for someone else's input on this issue please and thank you!
