is this a diaper rash?

we bought a different brand of diaper for our son, now two months old. the diapers had a powdery smell to them. 5 days went buy and he got red and earitated, within an 8hour period. I found a spot under the left side underneath the head of the penis,and it looked like a pimple, but it was bright white, so i rubbed it with a baby wipe and the white stuff kept coming out. It looked like ricotta cheese. after it all came out there was a small hole, and underneath the skin, you could see were the stuff was, it looked like an empty sack. I changed back to the brand of diapers I usually buy, and have been plastering him with corn starch powder, and he would really let me know when he was wet. today there is still a little redness around the base of the area, but it looks 90% better than it was. He also was bright red in the anus area, and that has gone away too.
   My question is what would cause a pimple or what ever it was,
to form like that?

This Forum is geared toward issues of child behavior, rather than pediatric medical questions. However, you should definitely have your son seen by his pediatrician. You observed some type of infection, and it may need to be treated.

sorry I put this question in the wrong catigory. By the way it wasn't infection, it had to do with being sercumsized, it was skin that had sealed it's self to the insition and dead skin had been caught in between, because no one told us how to properly take care of the wound other that putting vasaline on a gauze pad and washing him once a day. They forgot to tell us to pull the skin down from the crown.
