Hello,
I developed a white dot on my thumb went to a dermatologist and he said its a beginning of a wart and froze it off and gave me a cream. Few days later I developed ridges on my other fingers on the opposite side of my hand.
I have PTSD and OCD and trying to get back on my feet. I had a job interview that was successful for a real estate position. A position that requires a lot of shaking hands with strangers. Strangers saved my life after I was stabbed 5 times with a 13" knife a few years ago. I don't know if the ridges on my hands are warts. The doctor said the white dot isn't contagious anymore after treatment but he still needs to examine it. There wasn't a wart just a white dot that was a beginning of one.
