I have been having pain in my lower left abdomen for about 2 years.I always feel nauseous all day, but the worst in the morning.I vomit most mornings and it is either yellow, stringy, and strong smelling like ant poison Or it s undigested food from the previous night. I never have normal bowel movements. I usually feel constipated, but if I push on my abdomen to the left of my naval, it helps move it down. I don t have an appetite and have lost weight recently. I always have horrible gas and feel better when released. Lately, I feel sharp pains in the abdomen all the way to the rectum. When I work out it feels worse and I am a mover so I am always liftingI have had an ultrasound, a cat scan, a colonoscopy and upper and lower endoscopy, they have done blood work for my pancreas, been to er twice and they can t find anything wrong.My doctor is having me try high fiber diet and omit anything acidy.She is having me try dexilant for a month, but so far is not working. i also having been taking Gaviscon Extra strength which helps some what better. I am only 33 and have been miserable for so long
