First off.. I do have allergies, but my drs and I believe that it is not related to it, because I have no other symptoms.
Over the past 3 weeks I've had bouts of uncontrollable sneezing, up to the point where I've passed out from sneezing and also vomited. They checked me for whooping cough, and the test hasn't come back yet. They also think that there may be something in my brain misfiring causing all the sneezing, I have been taking muscle relaxants and also a medicine to block the mechinism in my brain from thinking it needs to sneeze. I have been taking the meds for two days and the sneezing hasn't lessened.
It is somewhat like a cough sneeze and the sneezing fits usually consist of at least 20 sneezes in rapid sucession.
