Recurring problem1st finger above the knuckle has what appears to be a pimple. Is it weird its on my finger?

every month or so my 1st finger above the knuckle get what appears to be a pimple with a whitehead but no pus and i can%26#039;t pop it. (sry to be gross) I also have had one at the same time on my right hand then it goes away. When it goes away it leaves a dry skin patch. What the heck is it????|||it could be a small wart. get some wart remover and try that out.|||It%26#039;s probably just an infected hair follicle. (furuncle) Wash your hands regularly. They%26#039;re usually caused by staph. and go away on their own.
