I did a Sinus rinse. I got water in my ear. Since then, my ear has been blocked (for more than 5 hours). What should I do?

If you have water trapped in your ear after a Sinus rinse and it has been more than 5 hours, you can try a modified Valsalva maneuver to help the water drain from the middle ear to your throat. This involves plugging your nose, closing your mouth, and blowing out while swallowing quickly. This technique creates a negative pressure that can help move the water. You can also consider using a decongestant spray like Dristan or Otrivin 30 minutes before trying the maneuver for better results.
