If you have real tinnitus, not sure if this works for these temporary symptoms you can beat the base off your skull with your pointer fingers by snapping them off your middle fingers. Makes the tinnitus shut up for about an hour usually.

You put the palm of both hands over your ears and make sure the two middle fingers meet up in the middle at the skull base. Then you simultaneously drum each finger against the base while keeping the ears covered, by making a snapping motion off the middle fingers with he pointer fingers. If it doesn't stop I'm 20 seconds, wait 5 minutes and try again. If it doesn't work on the second go, it's not going to work that day.
