All of a sudden I been getting sharp pain in my lower pelvic region going into my side and stomach and going pee makes it hurt worse what can the cause be also I took extra strength excedrin and it still not work

Could be appendicitis?

Or a kidney infection or stone?

It may be your bowels, gas causing pain in there.

See a doctor and have that ruled out. If your appendix is irritated that needs to be taken care of right away.
