i think i have "crabs"

[Tread]

I needed long to find out what crabs are. I thought of the hard shelled animals with claws. But they were a bit big to stay unseen in your pubs.

If its crab lice, don't worry, they are not dangerous, just bothering.
There are insecticides like Pyrethrum to get rid of them. Most chemical have adverse effects.

The cheapest and a harmless way would be to shave your pubs and comparable hair (underarm hair, and maybe body hair). If there is no hair they can grab, they can't stay on your body (Head hair is usually to thin for them).
They don't life long without human contact (about a day), but changing and hot washing of clothes, bedclothes and towels may help.
Crab lice like it warm and wet.

If its crab lice, you would usually see your skin colours blue or red, and could possibly see the animals themselves.

I would go to a doctor, but I don't know much about the U.S. health system.
