Hi thanks for youir qiestion.
Your are having pain abdomen and burning sensation.These are symptoms of acid peptic disease(APD).You had endoscpy one year back.What was your H Pylori status?( it is a bacterail infection of stomach picked up during endoscpy and is respponsible for APD).Antibiotics itself can lead to gastritis
( inflammation of stomach).APD usually don't lead to cancer.I would suggest you to consult nearby physician and get your H Pylori status checked by repeat upper G i endoscopy
You may need treatment for H Pylori eradication (if presennt) and gastritis.You should avoid other causes of APD like cigrette smoking
,alcohol,spicy food and drugs espicially pain killer.
Hope this answers your qiestion.
