I keep getting these symptoms every month or so.. I have been to my doc and he said could be thrush..(which he treated) but later said it could be due to a tear in my ear which filled with puss... I have no ear ache this time round, but I did get blood blisters on the roof of my mouth 2 days ago.. could this be linked. I keep swallowing all the time and my throat is very very dry but my mouth feels normal. My toungue feels like it has pins and needles and is swollen.. it also has a coating of fur on it.. I'm really worried about this as I smoke..
