Hi, Thanks for the query to H.C.M.C.
Above mentioned causes are sufficient to produce esophagitis
or hyper acidity) , you can call it as heart burn and symptom begins from mouth to stomach as nausea, vomiting
, sore mouth,chest pain
( because esophagus
is in the chest), excessive burping, bloating, knot formation ( seems to something stuck during water drinking).
Perhaps you would have understand your problem and disease.
Each and every tests will come out normal or within normal limit.
If you want to get rid off this disease pl avoid all causes which are responsible for your condition.
Consult a physician and have a treatment but precaution is the best treatment.
Good luck. Dr. HET.
