5. Sinus infections can cause eustachian tube dysfunction.
Sinus infection causes the eustachian tubes to fill with mucus or become inflamed. Using a saline nasal spray is helpful to relieve sinus infections.
The mucus needs to be drained and saline nasal spray will do the trick. It will take about three days to get rid of the infection and open the eustachian tubes. Blowing and pinching the nose will help open the eustachian tubes and get rid of the mucus.
With a sinus infection, antihistamines and Ibuprofen are good to take as well. You should still get plenty of rest when you have a sinus infection because the more rest you get the quicker you will get better. It is a good idea to stay home until the eustachian tubes open because if any air gets into the ear canal, it will take much longer for the tubes to open.
