Disclaimer, not a Dr and not giving medical advice. Just looking at your situation as if it were me experiencing it.
I saw someone do this on a flight and I don't know if it is safe so search first, but they held a tissue in a cup with a bit of hot water sealed to the ear so steam went in and it popped.
Actually let me look. So I see it is a thing on tik Tok. I saw it on a flight and I see some articles about it but I don't know if it would help you or not. I did find this article which has some ideas of things that might help.
