I have the same issue, as soon as i wake up
in the
morning. and preparing to go to washroom, i can feel the
sneeze thing is about to happen. my nose starts kind of internal itching and then i sneeze for almost 4 to 5 times. this is happening for almost 7 to 8 months now. I consulted a doctor once , he gave me some anti-allergic bu those didn't worked actually. I wonder if you have figured out some treatment for this.
