If your hip or knee pain seems to flare up every time the weather changes, you're not imagining it.
One of the most common things I hear from patients with arthritis is that they can "feel rain coming" before it arrives. There's actually a physiological explanation for this. When barometric pressure drops, which happens before cold or rainy weather moves in, the tissues around your hip and knee joints can expand slightly. In a healthy joint, that's not much of an issue. But in a joint where cartilage has already worn down, that small amount of swelling can put extra pressure on already sensitive tissue, leading to increased pain and stiffness.
Cold temperatures also cause muscles and tendons around the joint to tighten up, which reduces flexibility and can make movement feel more difficult and uncomfortable than usual.
This doesn't mean arthritis is getting worse when the weather changes, but it does mean your symptoms are more noticeable. If you find that weather-related flares are becoming more frequent or more intense, it's usually a sign that the underlying arthritis has progressed to a point worth evaluating.
