Hi Dear,
Welcome to HCM.
UNDERSTANDING YOUR CONCERN.
Thanks for your query.The symptoms you mention in query are due to consumption of energy drink.There is very high amount of caffeine present in these drinks which is known to cause stomach problem.They cause gastiritis ,which will cause inflammation ,pain ,ulcers and sometimes bleeding in stomach .
You mention that you had is with empty stomach which gave synergistic effect.
I would suggest you to consult gastroenterology without any delay .Doctor may prescribe
proton pump inhibitor like
rabeprazole to reduce acidity,H2 blocker like
ranitidine to block acid production,
antacid and some laxative.
What you can do now is avoid acidic and spicy food,eat small meals including banana ,take painkiller like
ibuprofen and some yogurt .And avoid drinking energy drinks as they do not suits your stomach.
Hope your concern has been resolved.
Get Well Soon.
Best Wishes,
Dr. Harry Maheshwari
