You say still some minor ETD symptoms but does the doc say your ETD is gone? What minor symptoms?
As far as the rest of your listed symptoms go, you may be over-analyzing your body in fear, so if you can relax they may all go away.
Celexa is a bit of a drastic solution compared to therapy - what dose are you on, have you used other anti-anxiety meds and how long ago did the ETD start?
Were you anxious before this problem started or only because you were scared of not knowing what was going on? Because Celexa won't help your physiological situation only, it will only help if you actually have a chronic anxiety problem. I don't really know what the problem was with your Eustachian tubes, but clogged ears and sinuses can cause disorientation and vertigo, and that feels like anxiety symptoms. But anxious people are anxious thinking people, and that's why I ask if you were feeling anxious before this problem arose. If not, don't understand the celexa.
