Hi momlovetobake! I am 28 and have had RSD for almost 2 years. I had the blocks done but they did not work for me either. My doc tried a inpatient epidural drip which worked while in was flowing but after going home it might have been a week before it was back with a vengence. I now have the spinal cord stim. For me it works great but the battery is very sore and sensitive. I dont know much about the pump. Good luck to you on this journey! I wish you the best!
