I am not sure why you could not get an appt. with Dr. Cahill. Just to clarify it is Kevin Cahill on 5th ave. NY, NY. I got an appt. fairly quickly (within 2 weeks). Keep trying. As of right now I don't think the visit has helped me as of yet. He pretty much ignored by nasal itch which the Tindamax (Tinidazole) will likely not resolve - if anyone can correct me on this please do so.
I will update if I learn anymore. Thanks for responding.
