divergirl, this sounds very likely to be middle ear barotrauma. When you delay equalization, you allow a relative vacuum to develop in the middle ear. This quite literally sucks fluid out of the cells that line the air space, and can even rupture small blood vessels and cause bleeding into the space. This fluid takes several days to a week or more to resolve, and while it is present, it impedes the transmission of sound waves through the middle ear structures, causing muffled hearing and a sensation of fullness.
There's nothing which has been proven to speed resolution of the problem, although the use of antiinflammatory medications, decongestants, and even chewing gum have been recommended. Prevention is the key, which means equalizing BEFORE you have any discomfort.
I would highly suggest watching THIS (long) video, which is extremely educational regarding divers' ears and ear issues.
If muffled hearing persists more than a few days, you should make an appointment with an ENT doc for an evaluation.
