My stomach bloats when i eat anything and any amount, even small amounts. I have food intertolerences but I manage them carefully and this does not feel the same as prior episodes of my interolerences. I am having stomach cramps on and off and also have a sharp twinge pain on the lower left back.
Hello, I had gone through the case and found that it might be intestinal obstruction or celiac disease. For left lower back pain might be renal stone, large intention infection or constipation. So go for ultrasound of whole abdomen, liver function test and colonoscopy and celiac and lactose intolerance test. After getting the proper diagnosis take treatment by gastroenterologist. Hope my answer will be effective for you. Thanks
