Puncture wound - prickly skin but not red or swollen.

[HarrietSchulenberg]

I put my hand on something sharp, perhaps a thorn, when I was out earlier.
I was untangling the dog lead from barbed wire at the time so it could have been a barb, but I think it was a thorn when I put my hand on the ground.
It immediately stung but there was no redness or sign of a puncture.
It's been tingly all afternoon. Still no redness, not swollen and no obvious sign of puncture.
So far I've taken Piriton, cleaned the area and slathered it in antiseptic cream.
So why is it still sore, and getting sorer all the time?

Could it be a sting of some kind? either plant or insect?.

I'm not sure but it still prickles. Have googled tetanus just to cheer myself up but I don't seem to have it.
