The brain has two halves or hemispheres: right and left. The right hemisphere controls the left side of the body, and the left hemisphere controls the right side. In most people, the left hemisphere regulates language and speech, and the right hemisphere controls nonverbal, spatial skills.

A variety of medical conditions (allergies, viruses, colds and upper respiratory infections) can cause fluid to collect in the Eustachian tube and/or middle ear, leading to congested ears. Ear congestion symptoms may include: muffled hearing, pain, inflammation, discharge, swelling and/or itching. This type of congestion typically resolves itself within 48-72 hours. Most of the time, ear congestion is not uncomfortable, but if you experience constant ear pain and/or discharge, it is important that a medical professional be contacted immediately.
