Although RA is usually bilateral it isn't always immediately bilatteral. My right knee was my first swollen joint and it was several months befor the left joined in. When I have flares that is how it usually works one knee then six weeks later the other knee. I had inflimation in my right sholder on and off for a year and then a year later in my left off and on for a year.
Go figure! the disease is just weird.
