You might be having peptic ulcer
or gastric ulcer !
The more severe ones are not relived by just antacids, they require some local anaesthetics too, with some stomach Ph reducing drugs and some anti bacterials which kill helicobacter pylori
, the main cause of peptic ulcer .
Another advice is to consume less spices (and less alcohol if u r consuming at all).
get well soon
