Odd Blister Situation

Hard to know how this happened--I blame a faulty liner in my shoe--but while dancing Sunday night, I developed a blister on the bottom of my second toe on my right foot.  It got worse when I went for a 45-minute run yesterday (one of the longest runs ever in my entire life, but it felt good), and then it became a lovely pink open blister and I limped around my apartment yesterday evening.  I don't like putting Band-Aids on blisters, so I'm just waiting for it to heal up today and not going running.
