Weather can have a big impact on joint pain.

I have heard her doctor talk about changes in atmospheric pressure being the cause.

I was curious to find out more.

I found some interesting information in Brenda Goodman’s article, Weather and Pain, published on Arthritis Today.

Changes in temperature or barometric pressure, a measure that refers to the weight of the surrounding air, trigger joint pain, though researchers aren’t entirely sure why. In 2007, researchers at Tufts University in Boston reported that every 10-degree drop in temperature corresponded with an incremental increase in arthritis pain. Increasing barometric pressure was also a pain trigger in the Tufts study.

In fact, studies in cadavers have found that barometric pressure affects pressure inside the joints. In one experiment, when pressure in the hip joints was equated with atmospheric pressure, it threw the ball of the hip joint about one-third of an inch off track.

Does this make sense of what happens to your child when the weather changes? What has been your experience?
