I have a very strange and uncomfortable sensation in my mouth. It feels as if the whole roof of my mouth is swollen and numb, and is also extremely sensitive! My gums look very swollen and the inside of my lef cheek is super red and blotchy, it almost looks as if I've been biting on it really hard but I don't think I have. There is no pain in that area though. This just came completely out of the blue literally in two seconds yestereday after chewing some gum and feeling 100% normal all day. I frequently get really weird mouth problems but this is the weirdest! I really want to resolve it and find some relief, does anyone have any advice or know what this could be? Thanks! (Ps. Ive never smoked and don't drink just fyi)
