It works!Blowing up a balloon with each nostril is initially a strange process but it seems to have done the trick. Your ears pop and crackle during and after each inflation and to get the correct force to achieve this, the balloon must be replaced regularly as it quickly becomes too easy to inflate, however after the initial purchase that contains 5 balloons I noticed a huge improvement and didn’t need to purchase any further replacements. As an adult suffering from glue ear, I would definitely recommend this unusual treatment method.1
