Period pain. Suffered with that for years. Rested up on sofa tonight with hot water bottle & pain has subsided for now. Problem seems to be exacerbated with sitting. Yesterday I thought it was the act of going to the toilet to have a wee or poo, but think it's more to do with sitting. Not sure what cause is if I'm honest, even GP wasn't convinced it was prolapse causing it. I've been not too bad since she referred me. I was in quite a bit of pain back then, but it slowly went away, apart from odd niggle. This last few days it's come back with a vengeance!
