Sounds like i have water in my ear. no pain or pressure. no vertigo. just a muffled, crackeling, sort of sound?

You could have: Wax build up that traps water behind it A trip to the doc will tell

Eustachian tube dysf: Need the ears checked. Could try using nasal saline and/ antihistamine like Claritin. Could be pressure on the Eustachian tube dysfunction

Serous otitis: You have fluid in your ears and it may take up to 60 days to dry up. Treatment is difficult so I would advise you to see an ENT specialist. He may want to give you a course of steroids to try to dry your ears out
