Welcome to our family. Like you, I have Lupus and Fibromyalgia. I do not have RA, but OMG, sometimes I ache as if I do.
I am happy that you joined us and you will find that everyone here is more than willing to answer any question that you may have. You are doing the right thing by wanting to learn as much as you can about all of your conditions. This will make you much more able to have informed conversations with your doctors and to be pro-active in your care!
We are happy you are here!
Peace and Blessings
Look For The Good and Praise It!
