Well, I tried a very well know wart remedy, garlic, and it seems to have triggered an immune response where a blister soon began to develop. It's about 1 cm long, 4 or 5 mm wide, and about 4 mm tall...

Is there anything I can do to speed the healing process? As I can't work out or play guitar until this thing disappears... Also, how much more quickly does a blister left alone heal than one which has been properly drained and bandaged?
