I am 20yrs old and female.Two weeks ago I started having upper abdominal pain (cramp like and intermittent) and bloating. Within two days my BMs stopped. Ive tried fiber, enemas, milk of magnesia, suppositories, and mirilax and have had only small soft lumps of green stool about the size a marble, about once every 1--3 days. It is very hard for me to evacuate even this small amount. I've had blood tests (bmp, cbc) 2 sets of xrays, and 2 urine tests and no one can find anything wrong. Is this just constipation or something more?
