I have over 5 years with a Boston Sci stim. Failed fusion, foot and low back pain.

Have they done any adjustments to your programming? It made a huge difference with mine. I would rate each program and decide to discard about half and try new ones. The tech would adjust based on what I felt. Made a huge difference on my feet and stopped the rib cage spasms for the most part. Also improved the low back issues. the feet were the target, programming and positioning rule.

Frequency was the biggest and most important change.
