Baking Soda Bath - One of the methods I've used when the itching and burning got so bad, that I'd itched myself into a frenzy, was to take a baking soda sitz bath. Baking soda is great for bee stings, wasp stings, or any kind of insect bite as well, as it helps to draw the "heat" out of the area. The same with an over-itching scenario. It's worked with poison oak topically, so I used it on myself in the nether regions and had success there with it.
There's two ways to do it, create a compost with baking soda and water and pack it on. If you find it burns, you might want to just rinse in a tepid baking soda bath. Don't fill the tub full of water, just enough to cover the places affected and then take baking soda and place it into the bath allowing it to dissolve.
The idea is to provide relief from the itching, so you can stop the itching cycle.
Apply Cider Vinegar -- Another remedy
that I've used is a apple cider vinegar / water rinse -- but if you've itched yourself too much this may sting. If that occurs, just rinse with clear water.
Plain Yogurt - make sure the package says "live yeast cultures" or it won't do any good. This is a cooling remedy that brings down the burn. You can apply liberally externally or apply to a tampon and insert. Yogurt's great for returning your body to balance. It contains the good bacteria known as Lactobacillus. You can also get acidophillus and ingest this. Acidophillus also comes in a buttermilk type drink of many flavors, this you take internally through the mouth. I've never tried applying it anywhere else, but it might work -- it certainly wouldn't hurt.
Liquid Aloe Vera - This type of aloe vera is sold at health food stores and in some grocery stores. Liquid aloe vera is an all around cure, for more than just ails a females nether regions. This can work to heal an upset stomach that has too much acid or can be applied external. If you have an aloe vera plant, cut a tip and use the gel fresh from the plant and apply externally. This is a very soothing ointment and it's always a good idea to have an aloe vera plant handy.
Garlic - Garlic ingested regularly can help to restore a body to balance. There's many a wives tales with garlic and the longer I walk the earth the more I realize that these wives tales, may not be tales at all, but a means to pass down valuable information.
Saline bath - add a little sea salt to your bath water. When I was kid growing up on the west coast on the Southern California beaches, I'd remember going into the ocean with skinned knees and elbows and coming out nearly healed after a few days. The ocean has incredible healing properties because of it's salt water, much like the amniotic fluid we all form in. A warm (or as warm as you can stand it) saline bathe will cure most ills. You can do this even if you don't have the vaginal itching.
Tea Bag -- We use these remedy on our pets as well. The tea bag is also a good way to draw the "heat" from something. Heat the tea bag and if you can stand it warm on your genitals, apply it, if not, cool it in the freezer a bit and then apply.
Anyone of these methods will help to still the itching and the burning and may provide temporary relief, yet more long term solutions may be what you're looking for.
