I've struggled with worsening rhinitis - difficult to typify, though triggered by a range of foods and cardio exercise - for over twenty years. I've tried most standard medical treatments, and had two surgeries, without much relief. I'd like to try a biologic (Xolair, Dupilumab, etc). I'm aware they're currently not indicated - though being researched - but know that some docs use them off-label. I'd also like to find a practitioner with AIT (SLIT, SCIT) experience. If anyone can recommend a doc experienced in using either/both, please reply. I'm in the Greater Philly area, but willing to travel.
