What do you think this is? I have a 6 yr old with itchy skin for about 3 days without hives or rash, fever, etc.... She has a chronic runny nose and takes Zyrtec but it doesn't help much. She had the Strep rash about 3 weeks ago so I think that I could see that if it were that. Using moisturizer doesn't help. Benedryl at night allows her to sleep.
