I came back to being allergic to nothing. We also did a blood tests for my thyroid, cancer,
graves disease,
and various other diseases. My thyroid levels came back normal but my auto antibodies came back high, over 400. The allergist said that its something we'll just have to monitor, watch my levels, and do 'a step by step' with drugs. Right now she has me on Allegra in the morning, Montelukast Sodium 10mg in the afternoon, and Zyrtec at night. It seems to keep the hives at bay.
