My trial for the Nevro implant lasted about 7 days and the surgery was done at the pain clinic. The anesthesia or sedation is given intravenously and the medication is typically is one that offers a quick recovery. I believe someone told me they may want to talk to you during the procedure so they can bring you to consciousness quickly. The other thing I remember is that you don’t remember much after the sedation so have someone with you take notes. Bathing is tough as you absolutely cannot get the device wet. The nurses said it was a sponge bath situation. I put a stool in my bathtub and washed carefully with my hand held shower head. My hair was washed bending over kitchen sink using the sprayer to rinse. I put a plastic bag over my shoulders to protect the device. We are an extremely clean culture but bathing used to be every Saturday night. I don’t think th nurses approved of all of my methods but no harm was done. Pretend your camping and roughing it.
As to why the trial can be better than the implanted device? I don’t know. I am going through that now-great trial, not there yet with the implant. The programmer said In the first months your nervous system is getting used to the signal so changes to the program aren’t unusual. Sometimes scar tissue may change the lead positioning. She said a difference of a millimeter in the leads positions can change the programming so with such a small margin for error the programs used in the trial are not going to work the same. That sweet spot is still there but needs to be found again. There is the slight chance that the leads moved during the healing stage. My device is in the cervical area serving the head, shoulders and arms and may be more difficult to program than the lower back implant.
The only other thing I can offer here is pay attention to the type of device you’re getting. Google the different devices and see what they have to offer for your type of problem. My brother in law is an anesthesiologist and his partners like the Nevro. (Pain doctors start out typically as anathesiologists and pain treatment is a speciality.). The nevro SCS affects a larger area, is radicular in its coverage or follows the nerve path through the limbs. It may be better for neuropathic pain according to him. Make sure your doctor is at least using it, some doctors are very conservative about newer medicine not a bad thing but these devices can last 10 years so do your homework and ask the doctor why this device he selects is best for you. I wasn’t offered the Nevro at one clinic because the doctor hadn’t looked in to it yet. The Nevro is a high speed signal and the Medtronic and St. Jude are a lower signal strength. Nevro has patented their signal so no other device can do that speed legally. The Nevro doesn’t have to be turned off while driving or sleeping because you never feel the signal. The lower speed devices can give you a tingling sensation when bending your body or turning your head, a distraction while driving and disruptive during sleep. Good luck, Cathy
