Nostrils clog while lying down. Is this normal?oK...this may sound stupid to you but Ive been reading in forums that many people have issues with their nostrils clogging when they lay down..i.e. when they lay on their left side their left nostril cloggs and visa versa...I am just the opposite...when I lay on my left side my right nostril cloggs up and when I roll over to my right side, my left nostril clogs....why might this happen? And wen I lay on my back both passages are open, left & right.
