Will my ears be ok after this gig?

Went to a get together the other night. I know about ear protection.
They had speakers blaring, so I got close to them for maybe 15 mins to
say hi to a couple people, when I realized I couldn't hear myself talk
or them talk, I moved away from the speakers.

Then they tuned it down, and I was away from them, but still like
30-40 feet away. I could carry on a conversation talking somewhat
loud but not shouting.

The thing that worries me is that I was around the loud speakers for
like 15 mins, then for another like 10 mins, then for another 10, and
another 10, with like half an hour to a couple hour intervals away
from them completely.

The next morning I woke up and my ears felt kinda full, from all the
noise.

Is it possible they damage my hearing? I tried to stay away from them
as much as possible?
I don't have any ringing, just that full feeling that's slowly going
away through the day...
