Hi, my arthritis started in my pinky finger right hand then went into my other hand,then spread into my whole hands ...and so on. So maybe a second opinion? I am for sure not a doctor,and still learning about
RA but I was told it can start in your hands and when its in both (symetrical like you have said happening to you) that its a good sign that it could be RA. Just wait a bit I am sure others will see your post and they may be able to help you more than me.
I am sorry you are hurting and wish you well. But maybe you should seriously consider another opinion? and well obviously you are doing research on your own which is good too!
Have a good day. ttys
