Been having serious lumbar issues for the past few weeks. Finally, texted my Nuvectra rep. Told him, today, I was having left lumbar issues. He made 5 big changes on my 4 programs to target my left lumbar. He added a 5th program. It is tonic. It targets the lumbar area where I had surgery in 2001. Sitting at home with no lumbar pain at all. This Nuvectra rep has been adjusting SCSs for over 20 yrs. So glad he's mine. He said to text him whenever. I get lifetimes adjustments for free. Good to know.
