Maybe a separate nerve entirely is being affected somehow? Nerves all are so delicately intereconnected.

If you are noticing that there's a pattern to how long after your cervical SCS is on that the problems begin, could you lower the stimulation prior to that point and see if that helps? Maybe lowering it for a while before it sets in and then raising it sometime later would give those nerves (or maybe it's muscle being overly stimulated) a break for a while.

During the cervical trial the first thing I noticed was that over the first few days the headache route started backtracking itself. First I stopped getting nauseous and lightheaded, and then my eyes started focusing better....like it was all shrinking back to my upper back/shoulder area. It was SUCH a relief to get rid of the pain in those areas. I've always said that I'd rather have back pain any day than deal with pain in those areas.

Good luck in tweaking. I'm sure I'm going to have a lot of tweaking to do once I get the twins.

Interesting how the cervical SCS can help the lumbar area.
