Hi, i have red ulcers on the back of my throat, and my right tonsil is swollen and has ulcers on it. i have had discomfort in my throat for about 5 months, i finally discovered the ulcers, and i went to my doctor. And antibiotics didnt do me any justice, it effects my singing voice, and i use to smoke weed everyday. i need help on what to do, cause i just want a healthy throat.
