I had an ultrasound but it was at the end of my period to check this out but they said nothing was wrong. I had a csection about 13 months ago. Every time I get my period, it feels like the csection scar is ripping on the inside, on my right. I don't know what it is causing this but I would like to know and how to treat it. It is excruciating pain and Tylenol, advil, and other medicines like that do not help. And cramps and moving makes it hurt worse, but it is a constant pain.
