Re: Hearing gone
The popping you describe is sometimes to do with partial or complete blockage of the Eustachian tube which can cause sensations of popping, clicking, and ear fullness and occasionally ear pain.
The eustachian tube regulates the pressure in the middle ear and drains away any secretions which is good when you have a cold or other viral infection.
It is often temporarily blocked due to viral infections.
If the eustachian tube function is poor air pressure in the middle ear can fall and the ear feels full and sounds are muffled which could be what is happening with you.
There may be no infection there now but it may have gone leaving a bit of an issue with the tube in it's wake.
I did have the popping noise earlier this year and I was worried that it would last for ever. It came and went and was worse in the early evening for some reason. It was there when I was going to sleep but it was gone in the early part of the day.
Eventually it went completely. I hope that is what will happen in your case.
When your hearing in the other ear is so comprimised you need that one functioning as well as possible. You might benefit from a visit to an ENT consultant if it doesn't get better.
Some people find that Sudafed decongestants and steam inhalations help a bit, it's something you could try possibly.
I don't think it's anything to do with the citalopram TBH, citalopram can cause aural sounds but they are more like feeling like you can hear singing etc, it's not a physical thing and it's part of getting used to medication which works on your brain chemistry.
Anyway good luck and hope it improves bit by bit.
