I had a small bowel obst. 2 1/2 years ago. Since then I have had severe burning abd. pain, nausea, vomitimg, bloating, and more severe headaches. I was treated for H. pyloris.I feel like I have to have a bm, but nothing but liquid, stringy, and mucus comes out I have no life. My Dr is still doing tests while my weight loss continues. I also have rectal bleeding. I feelso ill all the time. Any ideas?
