It sounds like your ear is blocked. My first jump my ears hurt like hell in freefall and until I learnt to pop them they wouldn't clear until the next day (mostly) Even then I found the pressure built up again a bit until they started popping on their own accord. It sorted itself out in a few days though.
I'm partway through AFF too and still land as deaf as a post but I pop them then, which helps. You could try that but just apply gentle, gradual pressure, by holding your nose and then gently trying to blow out of it.
I personally nearly have to blow my eyeballs out of my head to do it, but a lot of people seem to need less pressure. Don't do it hard and fast, you can blow your eardrum
