Hi, Thanks for posting your query. Are you getting pain while swallowing? Do you have acidic belching/ burning sensation in chest/ abdominal heaviness/ fever/ cough with sputum? With the available described details, there appears to be high possibility of drug induced esophageal ulceration. You should consult with internal medicine specialist/ gastroenterologist and should go for thorough check up. You should also go for complete blood count, blood sugar, thyroid profile, and renal function test. You should also go for chest x ray and endoscopy for better clarification. Meanwhile, you should also take proton pump inhibitors along with prokinetics and antacids. You should also follow dietary changes like; avoid tomatoes, citrus fruits, onion and garlic. Take soft diet along with curd. Take care, Dr. Mayank Bhargava
