While on our trip to Europe, Greg and I did a lot of walking.
And, all of the walking ended up being very... er... uncomfortable. My feet hurt, my legs hurt, but what was most painful was the chafing.
By Day 3 (at least I think it was Day 3... it's all a blur now), it was almost unbearable.
So... we used Google to help us out with our issues. After all, Google knows everything.
Greg read that if one uses deodorant on the affected areas, it will help with chafing.
AND IT WORKED.
Not only did the skin not hurt at all the rest of the trip, it began to heal.
So... if you ever have this issue, slather your skin with deodorant.
