I looks like a low reading, like when the Santa Ana winds blow through, is my trigger. Stress is the other one :(
I concur with these gals completely

I live at the beach so my altitude is about 90 ft. The reading right now is 29.90 in. which is exactly 1 atmosphere. The readings range from 28-31.

So is 28 or 31 a higher pressure reading?

We do have to be careful opening some carbonated bottles because they do bubble over from the pressure change of where they were filled vs. here at the beach.
Sometimes my ears even ‘pop’ when I drive from inland over the hill back home to the beach…ok you can call it flying the way I drive ;)
