Hi welcome to HCMForum. As your description suggests it appears to be oesophagitis.
due to gerd
. When you take some drinks oesophagus constricts and pain results due to
vagus nerve stimulation
. I advise you to consult a gastroenterologist
for diagnosis and
treatment. You may have to go for tests oesophagoscopy and scaning along with other
tests for confermation. Besides i advise some diet recomendations as Take more of
curd and bland foods. avoid taking spices chillies oily foods and junk foods. if you are
using bleeched water try to avoid it by drinking boiled water. I hope you are satisfied
with my reply. thank you.
