Why do you itch or have a burning sensation while running?

Question

I went for a run last night, about 1.5 miles. Just after I started, I began to feel a burning sensation in my thighs and across my lower back (above the butt). As I began to sweat these areas also began to itch. Why is that? I've also noticed before when I ran I would get the same feeling. I am not running at a HIGH speed, more like jogging and at the beginner's pace... very low-key. Didn't have on anything bulky, just some knee length sweat pants, bra top & tank. Any suggestions why this would happen?

This tends to happen in the cold, yeah? It's just tiny blood vessels opening below the skin surface as you warm up. Nothing to worry about.
