Welcome to HCM.
You could be having stomach ulcer
. You need to get a gastro-duodenoscopy done to examine the inside of your stomach and duodenum
and if an ulcer is found they will do a biopsy from that site for histo-pathological examination.
In addition an ultrasound
examination is also advisable.
The condition may or may not be serious, depending on the finding.
You should not ignore it. Consult a Gastroenterologist
Wish you all the best.
