I ate a very hot chilli a week ago and the same night my stomach was on fire and bloated , and since then my upper and lower abdomen is constantly bloated tight and hot especially after I eat and when I lie down which stops me sleeping also there is no pain and just mild nausea at times ..also my stomach acid was coming up into my throat for a few days after but has reduced now but I’m now coughing up green phlegm and my nose is burning ? I visited my doctor and he said it was gastritis and gave me Lansoprazole but it made me very anxious so I stopped . I’m not so sure it’s gastritis as I don’t have any pain just bloating and heat and a tight feeling, could it be h pylori or something else ? ..please can someone knowledgeable in this field help as it would be most appreciated..thankyou everyone
