I recently had my 22 month daughter in because she's had untreatable what I think is cradle cap but also, more importantly, a diaper rash ? that has been there since Feb. This rash is at it's worst now as she has a few vaginal ulcers that are painful with urination. The dermatolist is running a viral culture on the area. I'd like to think this is something like psoriasis but could she have genital herpes....I, mom, have had this for almost 15 years now. I have dveloped small postules of itchy fluid that has gone undiagnosed on my dominant hand, the one I diaper with. I'm a mess....can anyone offer me anything?
