Hello,a gush of water flowed into my ear, it hasnt flowed out yet. now i have hearing problems and minor periodical pain. what can i do avout it?

Antihistamines: If fluid is trapped behind the ear drum, it is usually a result of inflammation of the Eustachian tube, a conduit that allows fluid that bathes and protects the cells of the inner ear to drain into the throat. Pain caused by trapped fluid can be relieved by reducing the internal fluid level and inflammation with antihistamines and in extreme case antibiotics and steroids.

External Otitis: The water in your ear may have caused a mid case of otitis externa also known as Swimmer's ear. It is not conceivable that the water is still in your ear. The other possibility is that cerumen (wax) was moved around by the water, now causing problems in our ear canal. You should see a physician may be an ENT.
