Welcome to HCM.
Pain above belly button could be due to duodenal ulcer
and the pain in the left breast region could be due to gastro-esophageal reflux of gastric juices.
To confirm the diagnosis you will need to undergo an ultrasound
study as well as gastro-duodeno-endoscopy
Consult a gastroenterologist
, who will have to do a detailed examination and various investigations to arrive at a proper diagnosis.
Once the diagnosis is made treatment can be started accordingly.
Meanwhile avoid hot spicy food and eat frequent small meals and if possible have milk as well.
Wish you speedy recovery.
