you need to stop anything which causes acidity. this is Gastic ulcer

See your doctor, stop smoking, and eat non acidic foods only.

I would suggest seeing a doctor who specializes in digestive disorders.  No one can diagnose what is wrong with you just by reading your symptoms posted here, only a doctor can.

I have 3 gastric ulcers that tend to come back quite frequently.  I get severe burning in my stomach, chest pain in the middle of the night, pain down the left side of my arm, nausea and headache when they are acting up.
