i have had patulous eustation tube since i was 11 and am now 16, so 5 years, can be in both ears but mainly right. doctors have never diagnosed it right untill now, and have given medications for the reverse problem and just making it worse! no-one's ever said a true cure but would like to know more really. it's not nice to have atall! although i've found it can help by moving your ear down which i believe removes pressure and stops the symptoms for a while. i also get regular migranes, almost every day, which i believe also contributes to pet. the symptoms are there around 9 hours a day which is horrible. any more information....?
