Hi/ I have never had gas before, but I could not pass gas, a couple of days in a row I would pass gas by vomiting, no food comes out, just air. Now I have what feels like cramping of my abdominal muscle, close to the base of my penis. It feels like I need to pass bowels, but I do not. My bowels are soft. And it feels like the muscle cramping is connected to my anus. Not sure if it is just bad gas or do I ned to see a doctor.
