My son has had excama since 2 months of age and he is now only 15 months. But the excema refuses to clear up he cant sleep through the night and he is constantly itching..sometimes scratching his ankles to point of making them bleed. we have tried everything and the 2.5 % cream no longer clears it up. My question is how old were you when you started the allergy shots and how fast did it take to start working? also would you recommed allergy shots for a 15 month old? I hope to hear a reply Thank-you
