The inside of my mouth and tongue is peeling. It is not painful, but makes me feel sick especially when i find lumps of what feels like skin loose in my mouth that has unattached. My tongue and mouth is white but this white layer is easily and painlessly peeled off. I have a bit of a cough and sore throat and am extremely thirsty all the time. Could this be due to stress? What could i do to treat it and prevent it from happening again? Any help is much appreciated.
Yes, the stress add to the causative factors. Visit a Doctor for an actual visual of this or send us a good photograph. These lesions are best diagnosed on inspection. From your history these look to be fungal / oral thrush. Local antifungal oral application creams, antifungal tablets and check up to rule out diabetes and other diseases which reduce the resistance power of the body.
