Three months ago I had this same problem. My tongue was very sensitive, it felt like I had burned it with something hot. My Doctor put me on a low mg of antibiotics, then I had to go to urgent care when pain in throat got worse, he said my Doctor had not given me a strong enough anti biotic. He prescribed me 874 mg of Amoxzillin, which seemed to clear it up for a couple of months. In the meantime my family Doctor had me using Magic Mouth Rinse. Thanks, Billy Hagy
