I have had allergies and asthma all my life. When I have a sneezing
/hay fever reaction, it's accompanied by the usual itching of palate and eyes, and my medications take care of it. But once or twice a month, I sneeze uncontrollably, hundreds of times, all day long, and nothing, not Allegra-D, not Claritin, not Benadryl, will stop it. And the weird thing is, this sneezing is NOT accompanied by the usual itching. When I have a "sneezing day," I am nonfunctional.
