Hi doctor, not sure If i have genital warts, Tested negative for genital herpes, anyhow I tried Apple Cider Vinegar on what i presumed was warts (very small clump of 2-3 small bumps).. I soaked a cotton ball and left it on overnight with a bandaid...its day 3 and now the are with the cotton ball attached on my penis (right under the head by the cut) is black and feels somewhat burned...Is this Normal? any treatment to make this heal faster? any input helps
