I'm a 46 years old female,i have had a colonoscopy done the first time they removed 4 big poylps,2nd time nothing,last month was admitted over night,my DR.came in room and told me not to come back there was nothing wrong.. I look like i am 7 months pregnant,stomach stays hard and swollen 24-7. I have abdominal pain,stomach feels like its in my chest,i can't breath right,but not sure what is going on or what i should do..they told me last year i had a benign tumor,and a hernia,any help is appreciate.What is going on with me..
