Hi all, I was just in a bus and went to sneeze. I held it in just by closing my mouth and then googled ...now scared I've done damage. I didn't cover my nose and it happened so quickly it was spontaneous to close my mouth as it was busy. I'm so scared now....Google says it can do all sorts to your brain etc. I only felt discomfort for a few seconds. Would having the nose open she a positive thing.
