Mefenamic acid
"Like so many others I've had all the severe symptoms of endometriosis without actually having endometriosis. No form of contraception works & I've tried the lot. I'm now 36 and am going in next month for endometrial ablation. My Gyneacologist put me on Ponstan & another acid but it has not helped. Also I have horrible abdominal pain & bloating which keeps me up all night. I've had to stop taking it & need strong pain killers to cope. Forget going to work. Has anyone else had these problems? I'd love to know if these symptoms are more common than we know. Good luck girls!!!"
