Dear mel...I have been suffering from what sounds like the same red bumpd you are. I have been to many dermatologists and none of them have given me an exact diagnosis, so I decided to try to find something online. If it weren't for your posting, I probably would not have been able to find out what skin problem I had. After some more research, I have found a couple of websites that may help you find a treatment that helps you.
