Hello there, For the past few years (I would say since 2004) I have had a strange ulcer like swelling on the side of my tongue. I first thought that this is probably going to be a mouth ulcer and used everything from Bonjela Cream to various mouthwashes that were available in the local Boots Chemist. However the problem persisted and has got to a stage where every night I am awoken by sudden swelling of this ulcer (I call it an ulcer but its clearly something else as dehydration makes it much worse) tongue due to dry mouth, even though I always breath from my nose and drink plenty of waterbefore going to sleep. I am awoken by a pulling sensation of the tongue, which causes a sudden and severe pain. By checking on the internet it appears that this area I am refering to is the Foliate Papilliea area of the tongue and is affecting the left side of my tongue only. Could you please help me diagnose what this is. I have had mouth ulcers on both gums and tongue in the past and these have gone after a few days. Shamoon
