Hello and hope you are doing well.
If on examination the ears are clean, your symptoms may not be due to ear wax. There are tubes called 'Eustachian tubes' which connect the middle ear to the throat, this balances the air pressure in the ears. This tube can get blocked due to infections of the throat, which can give lead to a feeling of fullness in the ears and sometimes fluid collection, which can cause you sense a movement in the ears. The tubes can also be blocked in Eustachian tubes dysfunction. Here, the blockage can be intermittent. So, therapy should be focused on clearing this blockage.
Hope this helped and do keep us posted.
