Dang...
I woke up this morning with the left side of my tongue so swollen I couldn't even spit when brushing my teeth. It's almost back to normal now (3 hours later), with just a residual thickness in the left side of my neck just under the jaw line.
It's been several years since the last time I got these hives episodes. I hope they're not starting up again. For a while it was my left tongue, or my right upper lip up to the top of my cheekbone. My doc has no clue what triggers them, but Zyrtec seems to do the best job of getting me back to normal. It's not stress or food related...it just...happens. It's annoying as hell, though.
