On a particularly long and rugged walk this morning, my trusty walking boots of 12 years failed, and my feet got soaked. I didn't feel any pain at the time, other than a slight discomfort on my heels and I knew I'd got a small blister on each one. But when I got back I've discovered that I have a large blood blister under my big toe. It's almost certainly caused by the friction of wet socks, but I can't feel it. It probably covers half of the bottom of my big toe, and aside from the blister itself being blood red, there's no swelling or redness around it. I know that I have slight peripheral neuropathy, so while I'm concerned, I'm not surprised that I can't feel it. My question is - would this be a call to my DSN tomorrow? Or am I ok to dress it to prevent it from popping, and watch it carefully to make sure it heals?
