How painful is diaper rash, and how does it hurt?

On the 19th of this month my mom who is well aware of my fetish is going to take me to Wal-Greens, and K-Mart so I can use my Christmas money to buy some baby stuff.
Among these items is ofcourse diapers, and other changing essentials, and so there is a chance I may get diaper rash if I stayed messy, and or wet for to long which wouldn't be hard for me to believe if that were the case since I believe in milking oppertunities like this for all they're worth.
I just wanted to know how bad diaper rash was, and how it hurts.
Like what the sensation is exactly.
Like stinging, burning, aching, throbbing?
And if you could I would like you to rate how painful it is on a scale from one to ten.
Anyway hope I am not asking for to much, and well I hope you can satisfy my question with an answer, which I am sure one of you will considering how many stinky cubs we have running around here. ^^

I've got a heat rash that wont go away and it's irritating enough. The thing with rashes in that area, they can flare up at times. The pain scale jumps all over the place but I never had it go past a 5. It's just very irritating. Especially if your skin starts to peel. That's when it can hurt as you scratch the skin off. TAKE DEFENSES AGAINST THE RASH!

Don't. Scratch. Diaper rash. Seriously, it's PAINFUL if you scratch it-for me that's hard simply because I get really itchy when I've got a rash. I agree, get some rash cream and uuuuuse it >.>

Its more irratating than painful. It goes up a little on the pain scale when you try to walk because of the rubbing, but like the said use desetin or another cream to prevent it. I recomend getting Unique Briefs if you can afford them. They hold a lot and only recomend changing twice a day. Third time if needed. They expand like your normal diaper but dont leave the soaked feeling unless you use it near it capacity.
