I think it hurts enough to have people want to run, but lots of people take it without falling over in pain, so it must not hurt that bad.
I've heard of health effects being like blisters. The rays penetrate to the dermis of the skin, cooking the water molecules in the cells a bit.
Like scratching or slapping the back of someone with a 2nd degree sunburn is what I guess the pain is. Enough to make someone shed a tear.
