See a doctor. Other than the er which is not a place in which to undergo a diagnostic evaluation. What they may do is to tell you where else to go, but if it is not life-threatening they may just send you on your way. Go and see either a general internist or surgeon and get this fully evaluated. Hope you are better soon.
