I'm not talking about the mere feeling of a swollen tongue that comes when we focus too much attention on it, but rather a genuinely swollen tongue. Mine comes and goes. Two days ago it lasted several hours. Yesterday it was back to normal. Today it's been going for several hours again. I can tell by the way it looks thicker at the sides, and speaking is a bit more challenging. I have to concentrate to say 's' and 'th' words properly. I plan to see my doctor as soon as I can, and I'm hoping she'll refer me to all the right specialists.

I've heard it can be caused by hypothyroidism, a vitamin B12 deficiency, allergies, Sjogren's Syndrome, and other things. Has anyone dealt with this before?
