Re: 3.5 year old having unrecoverable itching disease
First I would wonder if he has a rash with the itching before scratching or just itching. Did they test him for food allergies? I would suspect food allergies first, especially if this started as a baby. Did he have a blood count done? Any other symptoms? Does he respond at all to antihistamines? I would take him off all dairy products and wheat/gluten and see if that helps. Those are the main allergens kids react to in diet. It may take a couple of weeks to see improvement. Has that ever been done?
