Pointe shoes killed my feet. I have a huge blister on my right heel with another blister on top of it, literally--on top! My left heel has three large blisters as well. Should I pop them or just leave them be? Thirteen years of dance and i've never had a blister on top of blister. Usually the inside of my blisters are clear colored, but the blister on top of the blister on my right ankle is milky white. So, should I pop them, let them be, or???
