See I used to run a "friendly" poker tournament at a local "coffee
shop" here in Chicago, and when these guys would start smoking, they would
start smoking...non stop. Cigars and cigarettes...non stop. When I left the place (after 3-4 hours in a not so well ventilated room), I would have a very mild head ache, high blood pressure, my heart would be beating like hell, and I would feel light headed...and I couldn't breathe too well. But I never experienced the pressure in the ears, it's certainly possible that it's not even related, but being new to ecigs, I'm trying to see if it's changing anything in my body....being slightly paranoid and all...
