What does it mean when your own blood makes your skin tingle?

I got a cut on my finger and licked it, the blood made my lips, gums, and tongue tingle, could I possible have poisonst blood? An STI? I mean it also made the skin around the wound tingle, so I doubt it could be an STI. What do you think it could be?
