A few weeks ago I started developing a small callous appearing issue on my left hand pinky finger. It is about ¼ inch in length a millimeter deep, is sore to contact and has tiny black specs under the callous.
At first I tried filing and trimming it back with nail clippers but the callous is tenacious. I talked to someone who is a nurse and they indicated it appears to be some type of fungus and to soak it twice daily in apple cider vinegar for at least a month and/or until it goes away.
I have included a link to take a look and any advice would be appreciated as my next step is our family doctor.
