Hi... Welcome to HEALTHCARE MAGIC.. I have gone through your query and can understand your concerns... As per your complain burning sensation in chest which was preceded with stomach ache seems to be due to hyperacidity leading to acid reflux in which acid from the stomach refluxes back to food pipe and throat leading to burning sensation in chest.. You need to consult a Gastroenterologist and get evaluated and he/she can also advise you to get endoscopy done and if acid reflux is confirmed you can be advised to take antacids like milk of magnesia or calcium carbonate, proton pump inhibitors like Omeprazole or Rabeprazole, taking small frequent meals, doing moderate exercises, drinking plenty of water and sleeping in left lateral position or with head slightly raised as compared to feet.. Hope this information helps.. Thanks and regards. Dr.Honey Nandwani Arora.
