Hello I appreciate your concern Looking at your history this could be digestive disorder like Acid peptic disease like gastritis or peptic ulcer and liver disease like hepatitis. I would advise you to take anti acidity medicines like pantoprazole or rabeprazole with antacids Have lemon water, yoghurt or curd as much you can take. If it persists or worsens book an appointment with an gastroenterologist for an endoscopy and a battery of tests like liver function test and an ultrasound you can take pantoprazole or rabeprazole group of drugs with antacids. I would like to know whether you have any risk factor for heart disease like family history or complaints of shortness of breath with palpitations or chest pains Waiting for your reply wish you good health regards
