Sting

I got stung by a wasp a few days ago.
It itches, it hurts, it swells, and it bugs me.
She crawled between my toes inside my sandal and committed suicide. It was only partially successful and I helped, once I got her out of there, and relieved her of her miserable existence. I whacked her with that sandal, I was angry. Its only natural. But her sting lingers on...
Anyone knows how to find relief? please let me know.
