What causes sore inside the mouth with white patches on tongue?
Patient: I have had a sensitive mouth on and off for about 8 wks. I have a sore on the inside of my right cheek (most likely a canker sore. I chew on that side and so salty and spicy food is irritating. The side and underside of my tongue has had some white patches and at the moment the (R) topside of my tongue feels like I ate something that was too hot (burned). Any ideas what I am dealing with. Doctor: Hello, thank you for consulting with healthcaremagic. The type of symptoms you are mentioning that you have sore cheek with white patches on lower side of tongue, it looks that you might be having an autoimmune disease known as lichen planus.Better that once you should visit an oral medicine specialist and get the necessary investigations done.Hope it will help you.
