When all else fails, scratch it good and bleach it. If I can catch it when it first starts to blister, I've beaten it by doing this. I'm one of the "sensitive" ones. Don't have to see or touch, just walk by and I've got it. Also, watch out for the blister turning dark or black. According to doc, that's when it gets in the blood stream and gets really nasty.(posted 9649 days ago)Kirk,
You have my sympathy.
