text: white bumps on fingers..itchy? suddenly the other day these white small itchy bumps appeared on my fingers..what is this caused by..what can i do to ease the itching? warts maybe? but if they suddenly appeared consider poison ivy, dematitis or maybe a fungus.  either way, hear is the treatments:  for poison ivy...don't touch anything and it will clear up within a week.  for fungus---use athletes foot creme on the site for about a week (once daily) for dematitis--- try cortisone creme for a week, twice a day.   either way, most likely it is nothing serious. if it is a wart...just use wart remover. but do this option last as it will take the longest to go away.
