Blocked Eustachian Tube Ear Doctor told me to take a breath and blow while pinching the nostrils. It works for a few minutes but then is blocked up again. I don't have any sinus allergies or infections. I can hear alright but would prefer to have clear Eustachian tube so I don't have that annoying cracking sensation when speaking. I tried the Nasonex spray and Medipot without success.
