Was to help knee's down to toes bilateral. It also went to my rear end and private area's. The 10th rate neuro in the country said to just get used to it. My pcp had some words back for him. It has caused it to spread to the areas it wasn't to go to. There are several links to the fact that SCS in severe cases of RSD only works for 3 hours to a few months and then is no longer helpful in all. Will post the links, if it is OK'd at a later date.
