<s>[INST] Hello, I use to feel stomach pain at my left side of my stomach. When ever I eat I feel uncomfortable and throw up. I feel something is stuck in my throat and I also belch and sweat when this happen. My stomach keeps on making some funny noise and also have sour mouth. My mouth easily get dry and I feel like Im hungry and normally bring out some gas by farting. Please what could be wrong with me. [/INST] Thank you for consulting with Chat Doctor. From your description of symptoms I'm included to think in terms of some kind of obstruction for the food passage from stomach.I'd also need some more specific details like-How much time does it take before you throw up after food intake ?-What is the consistency and color of the vomits ?-Does it pain when you swallow food ?-Is the difficulty more to solids or liquids ? These details would help me to make some more specific comments on your condition. The sour mouth could be due to nutritional deficiencies associated with your present condition. My advice is you get yourself examined by a general surgeon and get an upper gastrointestinal copy done if needed. Wish you good health. Please revert if you have further queries ? </s>
