Hi there :) I have had this clicking sound in my left ear - that I can also "feel" as well. It started about 6 months ago - after some dental work and a plane ride (don't know if it's relevant, just in case). It is present all the time - but I only really notice it when I'm in a quiet room, or when I turn my head to the left. Also very noticeable when I'm trying to fall asleep, or waking up - especially when I'm lying on my left side. It speeds up when I turn my head to the left- like the wheel of fortune wheel. I saw 2 ENT doctors, one said it was a muscle spasm (he also sent me for some tests - all came back normal), the other said he didn't think it was a muscle spasm, most probably "type-writer" tinnitus.
I really hate this symptom, it gives me a lot of distress - even more distressing is not knowing for sure what it is, as the 2nd doctor seemed unsure. I'm worried that there's something wrong with my ear, as it's a little weird that it started right after a plane ride (that plane ride gave me some ear pain and some popping), and that it mainly happens when I change my head's orientation. I hear that the vestibular system regulates motion, equilibrium, and spatial orientation - and whenever I move my head or change it's position is when my ear makes that clicking noise. I really need to figure this out.
Other info about me: I've had tinnitus - the ringing kind - in both ears for a long time - 7 years. Also infrequent bouts of benign positional vertigo.
Any suggestions or info on the clicking in my ear would be greatly appreciated, thanks :)
