Welcome to our family. We have a great bunch of people here. One thing about rsd is that is can be very different for each person. I understand what you mean about being kinda numb in different places on your arm. I have that on my feet, legs and back. I just try to avoid messing with those parts of my body. I am also on Lyrica and now Opana ER. I don't know which one of the two makes me loopy,but one of them does. In fact, trying to keep my mind focused and my fingers working is so hard.
Again, welcome and soon you will be almost everyone.
Hugs
Mary
