?? That sisters both have RA or being diagnosed in your 60s ??

It definitely can run in families. It also can hit at any age.

My mother has gifted it to her children

My great grandfather had it. Mom had picture of him he’s hand were so crippled up. Sad. Also grandmother on other side.

Sister was diagnosed 6 years ago at age 57. I finally got firm diagnosis several months ago at age 62. Runs in family. I was pretty sure I have had it for several years but put off treatment because I am already dealing with insulin-dependent Type 2 diabetes. Had to finally do something about the RA when it got worse.
