www.mayoclinic.com alot, but different ones have
pictures too, and they can tell you what to treat it with. If you don't find anything, to help relief your itching, you can take Benadryl, or one of the others that helps allergies. You can also soak in oatmeal baths. They sell it in a box of single packets. Hope this helps you out. Also check through this forum, I think there was a similair question with the same symptoms sometime back.
