Hot, swollen and a bit itchy. Turned up last night before bed, smaller and dark red. Dunno if it's a bite or one of those deep spots.
I've had hives like this on my face after eating prawns (allergic) but they were very itchy and there were lots of them. Haven't knowingly eaten anything I'm allergic to.
My only 'hmm' thought is that I have a dodgy cracked and crowned tooth directly under that. Dentist keeps a close eye and it was xrayed a couple of months ago, all fine and unchanged. But surely that would be painful somewhere?
