From past 2 months, I got swollen tongue 3 times at night. My tongue feels little itchy sensation that leads to swelling. It is really scary. Sometimes it is right side tongue along with lip and sometimes only left side of the tongue. It will last for 24hr. I have black kind of coating formation on my teeth. My tongue press against teeth. I have lightly burning sensation in my tongue. Nothing like spots . I am scared. Please help me out, it is making my daily routine hard. I never had allergic reactions before. I have gum bleed once. It is confusing that is it something related to my teeth or not or anything serious. Please someone help me with it.
