Semi-randomly, I decided to try the tea tree oil first. I painted some on with a Q-tip. By the time we were done with a bit of socializing and a walk in the park--showing off the park itself and some fine birds--the blister had shrunk enough that
So now I'm wondering whether it's a good idea to use more tea tree oil if I can't be sure the blister didn't break; if not, whether either aloe or Lanacane is suitable in that situation; and if it is a good idea, how often to reapply it.
