Hi, my name is Amanda. I have been recently diagnosed with RSD in my left arm. The doctors can't figure out how I got it. I have been struggling with it for almost a year now. I am on Percocet 10/325 3 times a day and I get ganglion nerve blocks every month to help with the sensitivity in my arm. My question is, My husband and i are considering having another child. I am concerned how RSD affects someone while they are pregnant. What pain medicine's are ok to take and does nerve blocks affect the baby?
