My right ear is completed blocked by earwax, and i have muffled hearing. i tried rinsing my ear under the warm water for 10 minutes but it did not help. what should i do?

Ear wax: See ENT. Have microscopic ear exam and cleaning. May need audiogram. May need treatment for ear canal inflammation/infection.

Dissolve it: There are many over the counter wax dissolving agents that can help soften & remove wax. They can be found in drug stores & drug sections of many centers. A dropper per ear left to settle for a while daily will help. If a week or so with this doesn't improve things see your doc for a clean out.
