Walking-huge blister on sole of my foot???

[sahs1969]

Any ideas how to ease the pain-I have been walking lots but all of a sudden last Fri took my trainers off and noticed a blister the size of a 50p on the ball of my foot by my toe-it is so so painful and just not quite sure what to do to it-as it's making my having to put shoes on and be on my feet all day very painful-plus I want to get back to walking tomorrow-usually do 20 miles a week :(
Any ideas

Something like this?

Compeed stuff is supposed to be good

Get a hydro-colloid plaster from the chemist. They are more expensive than other types but do work. I am due to walk a marathon on Saturday and talk from experience ;)

I used Tescos blister plasters having used Compeed et al. Was fine ... and really helped.
