Hello, I am 17 years old and 5' 4" tall and apx. 126 pounds and female. I am experiencing "bad" pain in lower stomach/pelvic area "during" my period and one time experienced numbness only on my right side in upper thigh and pelvin area when I proped up my legs on a pillow during the pain. I also had nasea at that time but did not vomit and was very restless and could not sit still or stand up straight. Wondering what could be the cause? Thank you
