This is a very unpleasant allergic reaction to flea bites which has the long name of papular urticaria.It usually disappears as a problem by about the age of 7 years. The rash is extremely itchy and difficult to treat.Caladryl is a good choice to apply to the sores and blisters.The best prevention is to give her a high dose of Vitamin B1 which is also known as Thiamine.Thiamine comes in tablet form and you would need to give your daughter a quarter of a tablet daily for 3 months. The tablet is very bitter so you will need to crush a quarter tablet and mix it with a little apple sauce.
