I think i am experiencing stomach problems due to stress. i've been feeling nauseous and having a constant feeling like i need to burp. how do i get rid of this?

Stress + GI symptom: no sensory nerve inside body, any symptom, be it pain, nausea, distension is from same stomach disease, and what you feel is milder than the disease can be really inside as you fell less than the gravity of disease. Resolve stress and altogether take meds that help stomach. Talk to pharmacist, use OTC med and use double dose to reach therapeutic dose while waiting to see your doc. Good luck!
