Anyone else suffer from prickly heat/sweat rash?

fShaw86

I've got miliaria, better known as prickly heat or sweat rash. Sometimes, I get a bit scared to sweat too much, because I tend to break out in extremely painful, itchy, red rashes. Get them on my neck, chest, and back most of the time. Hurts like hell, and I end up working out with a cold, damp towel around my neck just to ease the pain. Been powdering up before I hit the gym, and wiping off as I sweat (gets in the way sometimes), and taking tons of cool showers.

Anyone else go through this? What do you do? Thanks!
