Two days back, there was a sore in my tongue left side. I don't know how it happened or if i had bit my tongue. And yesterday at night 3 ulcers in mouth and another on right side of the tongue. And today morning i woke up to another ulcer in my mouth. I am unable to eat it pains so much specially that sore on the left side of the tongue. Also on the left side of the neck I am having swallowing pain. I can feel the pain in my ear too. I have a white tongue for years only the front side is red. Is it a problem?
