It is possible you have a blockage or congestion in one nasal passage and when you blew your nose after rinsing you blew too hard and put pressure on your ear drums. We always recommend that you do not do a sinus rinse when you have a blocked passage. You can try using a nasal decongestant spray before rinsing to open up the nasal passages, or wait a few days until the congestion goes away. Please, ALWAYS be careful to blow your nose gently after rinsing.
