This happened to me once on an airline flight years ago, and was accompanied

You didn't say how long it was since you got over your cold, but I can
tell you this. I had a similar thing happen to me, I thought I was over
my cold and apparently I wasn't. I felt fine, didn't have any issues or
anything, yet had a problem. A week later everything was back to normal.
That's a week after I had already thought I was well with no symptoms,
which I didn't fly until 3 days after I thought I was better. So it
actually took about 10 days from when I thought I was well to when
altitude didn't bother me.

My doctor said that you can still have a small amount of fluid buildup in
the cavities and not know it, i.e. have no symptoms.
