Since last 2 weeks, I have been suffering from bloating and indigestion. Initially, I had pain in my stomach at late nights, and bowel movements were not smooth. It was due to spicy foods, and food was not getting digested. Even after trying several home remedies and taking medicines(antibiotic, antacid, antihistamine and digestive enzyme syrup) for 3 days from a doctor, bloating hasn't stopped. I still have some pain at late night while sleeping. Not able to digest even fruits or little food. Stomach feels full and a bit headache. I think I might  have stomach ulcer or infection or something or even h-pylori. Please suggest a permanent solution or health check-up.
