Thanks for writing in.
I do not think that the cramping pain in the abdomen and sexual intercourse are related. I think the cramping pain in the abdomen can be related to irritable bowel syndrome
or some kind of infection which needs to be evaluated independently.
Sometimes, severe pain
can evoke a response where the blood vessels dilated and the blood pressure falls. This could be contributing to the pain you are experiencing.
Please see a physician for an evaluation of the cramping and then we can start with appropriate treatment.
Till then, I would suggest you restrict gluten
and keep a food diary to identify what is causing severe symptoms. This should relieve the cramping pain in the abdomen.
Hope this helps.
