Allergy and Immunology- thoughts on this specialty?

[pennpac]

I have an interview for an Allergy and Immunology position. I have worked in ortho and peds and am looking for a change as my current practice is not a good fit, I applied for what looked like a primary care position but turns out to be Allergy. Has anyone worked in this area and could it be interesting or is it the same old thing day in and day out. I don't want to interview for something if I don't think its a possibility but I want to have an open mind. I just don't know if this type of specialty would interest me but if someone can tell me there is more to it than antihistamines and inhalers I am curious to know. Thanks!
