Lately my tonsils have been swollen , red, and have had bumps . Its not painful , but I have never had anything like this before. My gums behind my back molar have had blisters and been swollen also , that started before my tonsils happened . I do have nasal drip , but its never cause anything like this before . I have tried rinsing my mouth with warm salt water , but it does not seem to help .
