Hi, i have a blocked ear. i tried fixing by draining it with water in the shower which didnt work and then hydrogen peroxide 3% which also didnt work. how do i treat this? also, i have had very mild cold symptoms for 2-3 weeks.

Eustachian problem: This sounds more like your middle ear is filled with backed up mucus. This sometimes happens with/after a cold when the tube that drains mucus from the ear swells shut. Yawning a few times may allow air to enter if your issue is minor. It would likely eventually self heal when the tube swelling disappears. If it persists see your doc.
