Red Rash On Legs

Often when I take a shower I am going out, and a rash appears stained pink-red, from my mid-thigh, stretching down to the bottom of my calf on the inside of my legs especially on the sides and back.

It disappears after 5-15 minutes. What is it?

I live in Colorado, but I know it's not because I regularly moisturize dry skin.

I'm like that too and I know that mine is the water so hot, thats probably your case as well. Reduce heat and see if it makes a difference .. Im sure there is not anything wrong if

I live in Colorado too, have the same problem, I thought that if I can shave and reduce the heat, I did not,

I suppose

1. Nuclear hot water in the shower (which is not very good for you)

2. An allergy to a body wash or something you use in the shower.
