Osteoarthritis can definitely be hereditary, both of my parents suffered from it, and myself and all 3 of my sisters have had to deal with it. Mine is the most severe, probably because I worked very physical jobs for 35+ years to make a living.

Yes, it is absolutely hereditary. My ancestors didn’t necessarily correlate it to the barometric pressure change, but I certainly do when it was pointed out to me by a doctor in 2009. He said it wasn’t the hotter the cold or the wind or the rain he said it was the change of the barometric pressure. Where I live the weather can change 25 to 50° over the course of the day and that makes a big difference to my body. There are some days I just stopped in my tracks. But I have two kinds of arthritis, the osteoarthritis, OA, and the gout arthritis. The gout arthritis reacts the most to the weather. Once I realize I had gout after 25 years since my first four flares now being on the allopurinol medicine helps incredibly! Food also serves as a flare and not enough fluids and certain kinds of alcohol. Pay really close attention to your flares. The doctors don’t! They only pay attention to things that are physically registered and also materially analyzed but not weird things like the wind, the rain change and things like that they leave that to be old wives tales!
