Today DS had his first appointment with the allergy/asthma specialist. The doctor said it is clear that he has allergies but the skin test came up negative. Thankfully, the doc validated what we saw behaviorally with the Singulair (he was, in two weeks, becoming more aggressive and having nightmares) so put him on Zyrtec and Flonase. He will use a controller med in the fall. Has anyone else had a child with allergy symptoms but no reaction on the skin test?
