I even have a story about Deodorant!
Around this time last year, I decided to save money and buy some Old Spice Red Zone. After a few days of using it, my armpits started to itch. I didn't think it was from the deodorant, I just thought they were dry or something. Popped some lotion up there for a few days and continued using the deodorant. A little while later (about a week after I started using it), I developed a rash. The rash got so deep and bad, I could barely lift my arms without crying in pain. Picking up a shirt from the ground was difficult. It was so bad, that I stayed home from School for two days due to not being able to move my arms and being in pain whenever I moved. I went to the doctors office, and he said that's the worst rash he's ever seen, in one of the worst possible locations for it. The shit was cracking and oozing. I cried when water touched it, and I had to rinse it out with a non-fragrant soap and water.
Here is a picture, I think it's pretty disgusting so be careful clicking the link:

That's the highest I could lift my arm without crying from it cracking and splitting. It was on both armpits as well, not just this one.
So now I use Degree Cool Comfort, and I will forever be sticking to it.
