If weather systems change quickly, the sudden change means the little bits of air or fluid inside your body are suddenly out of whack with surrounding environment and are either pushing extra hard, or are being pushed on extra hard. If you’ve ever driven up/down mountains or flown on a plane you’ve probably felt this in your ears as your ears pop. Some people also feel it in their knees or other parts of the body.Either way, your nerves relay the change to the brain as pressure or pain until the little air/fluid pockets re-adjust to the new air pressure outside your body.0Reply Share ShareShare on FacebookShare on TwitterShare on LinkedInShare on WhatsApp diabetomaximus Added an answer on May 21, 2019 at 4:48 am Normally when someone says they can feel the rain coming what they mean is they can feel the barometric pressure change0Reply Share ShareShare on FacebookShare on TwitterShare on LinkedInShare on WhatsAppLeave an answerLeave an answerCancel reply Attachment Select file Browse Featured image Select file Browse What is the capital of UK?
