The barometric pressure drops preceding bad weather. You will feel it in your bones because there is water inside your bones.....and it takes at least 24 hours to be equalized to the reduced atmospheric pressure in the air.



This is it. Drop in barometric pressure causes expansion from the reduced air pressure. Like makes them swell and then they hurt. Not always actual visible swelling but am sure you know what I mean.


Then why doesn't going up a tall building in an elevator or flying in an aircraft hurt the same way? The differences in air pressure are greater for the elevator/airplane scenario?

Just for the record I have had five knee surgeries and numerous broken bones, and cold, wet weather is miserable. Why? Beats the hell out of me and my orthopedic surgeon.



Barometric pressure is not affected by heights other than aircraft height.




What the hell does that mean? Are you saying that if I take a barometer to 18,000 feet it will read the same as at sea level?



No, I am saying that going up in a building, even a very high rise, will not affect barometric pressure ~ the pressure reading WILL be affected once you reach altitude, such as those achieved by aircraft.

The pressure difference 100 feet in altitude is negligible.
