While I know this more of an alternative medicine board, I'm going to suggest an alternative to Rx meds.
Several years ago my doc prescribed ANUCORT-HC (hydrocortisone Acetate 25mg) for this problem, I sat down and read the ingredients and low and behold over the counter 10% Cortaid has basically the same stuff, so when I ran out I applied the Cortaid to the 'problems' and low and behold IT WORKED! And the cost was MUCH CHEAPER!
I've heard of people that used a wedge of potatoe to cool down the "problems,' allow potatoe to sit in the fridge til cold, slice it to size and apply directly to the spot.... they swore by it, frankly I figure potatoes are better served when eaten.
