There is a video on Dr. Pipmple Popper that her husband did.... he removed a fingernail.I've had ingrown toenails before (from cutting them wrong and too short). I don't know really, it's fascinating. The guy I watch (the Toe Bro) is a DR in Toronto, so he numbs up his patients.
My brother has a cyst in his arm and I don't know how he leaves it alone.
Something was under it and they needed to biopsy or something. Even Dr. Lee couldn’t do it. LOL I think I’ve watched it once, through my fingers over my eyes. 
I can’t judge— I watch mango worm popping videos.
