Try some coconut oil first, its anti viral and anti bacteria. You can find it in most health food stores, extra virgin tastes like coconut, try a teaspoon first for 5-20 minutes and work your way up to TBL 2X a day. Try to use Sesame, Sunflower, Olive, or any nut oil. You will see some relief from you systoms. IMO with the itching your describing I would guess you need a parasite cleanse. The OP'ing will help with some forms of parasites, but you might want to invest $20-30 in a cleanse in addtion to OP.
