## Discrepancy

IT HAS BEEN REPORTED THAT DURING PUSHBACK AND TAXI FOR TAKEOFF, THE CABIN PRESSURE INCREASED 8 PSID BEFORE THE FLIGHT CREW BECAME AWARE OF THE ABNORMAL PRESSURIZATION.  THE CABIN CREW REPORTED PASSENGERS DIDN'T FEEL COMFORT.  ONE FEMALE PASSENGER REQUIRED HOSPITAL TREATMENT FOR A EARDRUM BLEEDING.  PRESSURE WAS NOT RELIEVED UNTIL THE ENGINES WERE SHUTDOWN.
