Thank you both very much. Dr's appointment in a few days. Hope an answer and a cure will be the outcome.
See a Dermatologist so you can know exactly what you're dealing with.
It could be fungal or bacteria. If the doctor doesn't think it's fungal, it could be bacterial. I've had that non-specific stuff before. It does get better. You might be able to get a prescription that treats fungal issues, which can easily occur in women. It is not necessarily yeast, though. It can be other fungal stuff. So, your doctor will need to get a sample, so you'll have to go through an exam similar to a pap smear.
The other big thing that can help is making sure the area gets plenty of air. Avoid polyester underwear. Use only cotton. That tiny cotton area on polyester underwear is usually not enough. Remove your spandex exercise clothing immediately after exercising. Gently "wash" or rinse the area without using soaps at all. When you're showering in general, use gentle, non-irritating soaps and shampoos for the rest of you, because such things wash down your entire body and will affect your private area, too. Avoid those antibacterial soaps and bodywashes. Those are bad for so many other reasons, but the triclosan and the scents and such are all drying and irritating to the skin. All that irritation will definitely only serve to aggravate what is going on in your private area. It sounds contrary to what you might think when you're talking about the sweating and the smell, but definitely don't even soap the area.
