I'm not sure if an SCS is recommended for those with Tarlov cysts since it could make your pain worse. Any activity in and around the spinal cord and Tarlov cysts including the SCS, injections, etc. can trigger worse pain. This is especially true if you also have arachnoiditis. The benefits sound great but I can't imagine my pain being worse. It depends on how much pain you're in and what's causing it I suppose.
