Dear madam, you need to go to ER if you feel constant pain, fever, bretahless, vomit blood or feel fatigue
but your symtpoms definitely means something and detailed work up should be done. You obviously have some kind of intestinal passage disorder
caused by either mechanical or non mechanical causes. YOUR GYNAECOLOGICAL PATHOLOGY U VE DESCRIBED COULD effect your intestinal motility and if there is a certain cause then pills wont be helpful. The best way to rule this out is to the colonoscopy
,barium swallow or diagnostic laparoscopy
and everything shoud be clear.
Wish you good health, Dr. Ivan Romich
