The left side of my tongue, upper palette, throat, cheek, lower lip and gums of back molars feel but do not look swollen. I am having difficulty talking without biting on my tongue. When I compare the right side of my tongue to the left side, the left side is a bit more pink/red. It began about an hour after I ate. I thought this might be related to food allergies (not that I have been diagnosed with any allergies). I took an antihistamine but it hasn't helped much.
