Heat and barometric pressure increases kill me. I actually used to live near Sacramento and moved to the Seattle area in part to escape the heat and pain. I can always tell when the pressure starts to rise, even a small amount, as the crushing pain/pressure increase, but overall I am MUCH better now that I'm out of the heat. Very cold days are uncomfortable as well, but this area rarely sees extreme temperatures in either direction. I think we hit 70º today...ahhhhh....

Here's hoping for cooler weather and some relief for you down there!
