Vagisil. you know, the female itch stuff. if you get the extra strength stuff, it has a good dose of benzocaine and costs less than the other itch stuff.
there is a new hemorrhoid cream out that is supposed to be good too, but i have not checked it out.
swelling is not a systemic reaction. hives, sweating, shortness of breath, itching away from the limb that is stung...face itches when stung on hand, are systemic.
