In brief: See below

It is the changes in barometric pressure as any fluid in your joints can expand or shrink with changes in barometric pressure.

In brief: Not per se, but:

If you have frequent bouts of rain or severe weather, a fall in barometric pressure preceding a storm will increase joint pain.

not too long ago in Germany, a study involving medical students with no known arthritis of the knees had barometric needles placed in the knee joints to monitor the barometric pressure of the synovial fluid which would rise and fall with changes in the barometric pressure.

First studies done in the early fifties by Joe Hollander using the US Naval Statiun in Phildelphia during the Korean war. First time underwater demolition divers were trained. He put arthritis patients in little chambers, and changed BP, Temp, and humidity! Only fall in BP produced pain, and the greater of faster the fall, the more pain! In Knoxville, as of this week, 47 inches of rain for the year. Normal yearly total 49". Rheumies doing well. Best, TCN
