I too have this issue with ears, aftertaste a 6 hr flight home I got covid 2 days later then these started: the ear fullness feels like full of water, pulsing, pain, ring in the ears ( Tinnitus). Sore neck muscles just want to sleep so I can’t hear ringing. Sleep issues happening now.
It’s been 6 weeks since covid and no better. Had antibotics for possible ear infection, Took myself to emergency dept at hospital due to pain unbearable saw ENT they said ear looks fine ear drum swollen just take anti inflammatories hmm.. saw gp after that was put on steroids (prednisone)for 7 days . No change. Been to see audiologist had full testing - mild hearing loss to right ear and tinnitus to both ears and advised to see ENT as soon as possible as ear drum not working at all . So now trying to Find an ENT that doesn’t have a long wait list here in Australia. At moment 6 mths before I can see an ENT. A task on its own.
No one does understand the pain & ringing in the ears how debilitating it is. And Drs just keep dismissing you and the symptoms.
All the best in your quest for treatments and answers.
