I had the same condition. Tapping my head sounded like tapping a watermelon. Echo'y and hollow sounding. Got rid of it in two seconds. Held my nose shut and then forced my breath against the closed nose. Left ear 'popped' and the worrisome condition completely disappeared. Back to normal.
I had the same problem. I just let the water from shower enter my ear, after showering the inside and shutting off the shower i kept the side of head with affected ear tilted to ground, jumped a few times to let that water out, and then drained the inside with a hair dryer for like a minute or two. It helped me instantly.
I had this same thing a few years ago and went to the dr. They flushed my ear with water and big was of earwax came out..it helped!! And got rid of the sound! I am getting it again...so I am hoping it will help again.
Thanks for the reply. The sound has since gone away, except for a few exepections after spending time in water or not drying out my inner-ear after showering/bathing/swimming. I have spent a considerable time of my life in water and never had this problem before so I wonder if I didn't have some sort of infection (which didn't pass on it's own) or just didn't dry out my ears well enough. In any case, thanks for the input!!! KB
I get the same sensation when there is fluid in my ears. See a doctor if it doesn't go away or especially if it gets worse (i.e. hearing loss, pain, draining nasty fluid, ect) because you could have an infection of some kind.
