your last sentence, I am trying to follow you...

The trial is a must, and it is programmed after the battery is placed on the exterior of the body. You can dial it up higher or lower during the trial, and I brought it up higher, but that was my mistake, as I woke up during the night "buzzing".
The rep's contact you daily, or at your service during the trial.
After the real SCS is implanted, I heard from other patients, their rep "ghosts them" and they don't hear from them again. Have a good relationship with your neurosurgeon, and as I said, if they do not contact you, contact the neurosurgeon and they don't want to hear it from the neurosurgeon, of why they are not in contact with the patient.
This is big business, and the two doctors I declined to have their performance, called me and asked me why I didn't elect to choose them (??) That to me is most unethical, and I was taken back when they did question me.
The SCS permanent placement is up to you and the surgeon. The second one inserted rides up higher than the first one.
Please keep all of us with the forum, updated with you and the process.
