Feeling of water in the ear, pressure, ringing, muffled sound?

Based on the symptoms described, it could be beneficial to use a saline solution for nasal hygiene, such as Hydrasense or Sinus Rinse. This can help with allergy symptoms and promote drainage in the sinuses. Additionally, an antihistamine like Aerius or Claritin may be helpful in managing the symptoms. It is recommended to use these treatments as needed throughout the day and before bedtime. If you have any further questions, feel free to reach out to a pharmacist for assistance.
