I suffer from anal pain during periods. every time i need to go to bathroom, the anus hurts me so badly,but it disappears after periods. is it normal?

Endometriosis: i wonder if there is endometrial tissue in that area which would cause those symptoms. Check with your GYN

Period: Hi, do you bleed from the anus, too while on period? If you do then you need to see a Gynecologist, otherwise having pain in pelvic area is very common in women, try to avoid constipation, take Ibuprofen every 4-6 hours, use a hot pack if not better you might benefit from birth control pills for awhile, good luck.
