Yes. I've had this happen twice, both prior and during my two MG crises. Here is a portion from a fax I sent my neurologist: "My sinuses are frozen. If I hold my nose and blow, I cannot get the pressure to change."

I wonder what would happen if, in this condition, I was driving in elevation. My ears usually pop when I hit the Summit on Highway 17, between Los Gatos and Santa Cruz. The Summit is only 1800 feet.

Welcome to the group. When I changed my screen name earlier in the year, I considered "pingpongboy", but went a different way. I was afraid that your brother would beat me up.
