Having just finished W9R1 I discovered a blister on the sole of my foot. It's on the heel and is about 1cm by 5cm. It is quite tender. That was on Wednesday. It hasn't got any better and I want to run either tonight or tomorrow with the aim of graduating either Sunday or Monday. So what should I do about it? I put a blister plaster on but that didn't seem to help. Should I pop it carefully with a sterilized pin, leave it or do something else?
Would appreciate any advise as really want to graduate in the next few days and would be gutted if something as simple as a blister prevented that from happening!
