The age-old question why does my knee hurt when it rains? Everybody knows somebody that can predict the weather based on their knee pain. Actually 67% of people with knee osteoarthritis believe that rain causes their knee to hurt so there must be some validity to it. If you want to learn the difference between arthritis, osteoarthritis and osteoarthrosis read this blog. Here are four reasons why a person with knee osteoarthritis or knee pain may experience pain:
- With rain comes a change in atmospheric pressure and that change in pressure can be sensed by damaged nerves in your knee that would result in felling pain.
- When it rains it's typically pretty cold outside and with that cold weather the fluid in the knee, called synovial fluid, can actually thicken and cause more friction and more stiffness.
- There's typically higher humidity when it rains and with higher humidity the painful tissues in the knee starts to swell and cause pain.
- When it rains typically you're stuck indoors and it's just not a very happy time and those mood changes can often lead to more pain.
