Have i been bitten?

[Christinedaae17]

Leg started Itching last night thought it was just my urticaria flaring up again as it looked like that sort of rash but about an hour later the bruise appeared, I sometimes do bruise if I've scratched hard but never that quickly! and there was one spot left with quite a sore head on it.

I don't recall being bitten at all so I'm at a loss?

Well you wouldn't recall being bitten because the bite is typically painless. It's the subsequent itching that's the problem

Something has nibbled on you for sure. Antihistamine may help.
