Hi,
I live in Arizona and three times now have mysteriously been bitten by something on the lip. My lip immediately gets a hard lump, gets numb, and swells insanely large! I can never see an actaul bite but the size of my lip is horrible. I thought it was one of those "kissing bugs" but then yesterday I got bit on my finger with the same results. Always the same... it stays numb for about 24 hours and the swelling goes away in about the same time. Does anyone have a clue what kind of insect or spider would cause this??
