Hi... Welcome to healthcare magic. As you mentioned you have problem of abdominal burning sensation that may be because of gastritis or ulcer or reflux problem or h pylori infection or intestinal infection or other reasons. More spicy food and alcohol drinking may cause this type of symptoms... Consult a gastroenterologist for further diagnosis. Endoscopy examination is helpful for further diagnosis... Start a treatment as per reason behind it.. Detail history and investigation give exact idea about problems .... I hope this will help.. Get well soon.. Thank you.
