I'm offering this information becauase, having read through many forum posts when I had the condition, I learned how challenging it can be to find a solution to this.
But I feel that once I figured out what worked, it was actually pretty easy and formulaic to deal with the condition.
First off, the apple cider vinegar on a cotton ball DOES work. I used this for three little bumps in my vaginal area. Yes, it burned and stung, and was difficult to get the cotton to stay on (had to use scotch tape overnight!). But it totally got rid of them.
To do this, soak a piece of cotton ball or gauze in raw organic apple cider vinegar, just big enough to fit over the bump. Tape/band-aid it on there overnight. You might do a couple nights, or daytime, if that works for you. The bump starts turning black as it's getting killed. These bumps went away and never came back.
When I did the cider vinegar on a couple spots on my leg, it left scars that I'm not happy about. Had I known at the time, I would have used CLOVE OIL instead (essential oil of clove). In addition to the cider vinegar, I found clove oil to be perfectly effective.
I diluted it 50% in another oil. Sometimes almond oil, sometimes olive. I don't think it really matters what other oil you use. And I'd rub it on the spots a couple times a day. This was very fast to clear up spots on my chest, legs, armpits (from shaving--don't shave affected areas as it spreads the condition), butt, abdomen. It seemed to kill them in about 2 days. I highly recommend working with clove oil FIRST, and cider vinegar for bigger bumps if the clove oil doesn't seem to be working. This should minimize scarring.
I also used terrasil on these areas with DMSO to make it absorb well. I think this was helpful, and I like to hit a problem from every angle with multiple remedies if needed. But I don't think the Terrasil is an absolute necessity. If money is tight, try the clove oil alone first. Dirt cheap, while the Terrasil is more expensive.
