Back in 2000 when I traveled abroad to Europe I got a swollen lump in my tongue (not visible), it did shrink after a few weeks, and I was left with a smaller lump. No pain. No sores. Then in 2010 when I traveled abroad again the lump did swell up again for about a week.
I'm wondering if something like this is maybe caused by an allergy? Or perhaps flying? lol I don't know. Anything strike a bell?
btw currently I am a white 29 female not a smoker or drinker but do have a thyroid condition (hoshimoto) and no insurance.
Thanks for your help and have a blessed day!
