If he is totally blocked his eustachian tubes may be involved which could cause bad pain and even a ruptured eardrum. He should discuss this with his physician. Please read our Sinusitis MedFact at http://www.nationaljewish.org/medfacts/sinus.html for further information.
His doctor may recommend the prescription nasal steroid spray. This can decrease mucus production and improve sinus drainage by decreasing the inflammation in the nose and openings that drain the sinuses. This generally provides a more lasting decrease in sinus pressure and improves sinus drainage. To get the most help from a nasal steroid spray use it after doing a nasal wash. Please read our Nasal Wash MedFact at http://www.nationaljewish.org/medfacts/nasal.html for more information about this technique. Share this information with your father’s doctor to see if he would benefit from this daily treatment. A nasal steroid spray does not provide immediate relief of symptoms. It may take several weeks of routine use to become effective.
Sometimes it takes an antihistamine, a decongestant, and the nasal wash followed by the nasal steroid spray ALL used routinely to treat a sinus infection or to prevent one.
