What did you use to moisturize? I'd use something called Healing Balm- I usually get it online from a company called Lemongrass. It takes care of a lot of these odd little rashes. If that doesn't seem to help, or you aren't sure you want to try it- head back to your doctor and let them know that what you are trying isn't working. Sometimes doctors need to be seen a few times before they get the diagnosis and treatment plan right.
