This time I've had a lung x-ray which was clear, and doc has tried Tessalon Pearls
, Zyrtec, steroid shot and Nasamist with very little success. I have several violent spells daily and several at night.. Tomorrow I am going to an allergist to see what I may be allergic to that is causing this post nasal drip that seems to be causing these episodes. I had whooping cough when a was pregnant with my twins in the 60's.
