My wife had the Nevro unit for Thoracic t9-t-10 as she is fused from ther all the way to her pelvis.

Do your research and then research somemore. These things are big dollar profit for the Dr's so they tend to push them for anybody.

They are mostly designed for lumbar as the leads are placed above the pain are so they affect the nerves before they go downward.

Make sure you find a Dr. that does a lot of implants of the brand you get and has a good relationship with the device reps as that is who will provide all of the support. Ask how long the reps have been with the company. You will be talking to them a lot, It takes a lot of tweaking to try and get the best result. They do this over the phone with you.

The implant surgery was done in an outpatient surgery center. Takes about an hour. She stayed in bed first week or so then gradually back to normal. Most pain was from the pouch they cut in for th unit.

They do a temporary one first. If you get relief they can do the permanent one.

This is my opion only from my experiance so take it as that.

They jacked the temp one to a max setting to try to get the best results in the short time of the temp unit.
Unfortunately this is not tolerated by your nerves long term.
My wifes temp was almost complete pain relief but she never attained this again with the permanent one.

It worked maybe 50% at the begining and then started decreasing over time. It was a pain to charge as the higher level of stimulation drains the battery quicker. We had to charge pretty much every night.
There is a charging pad that is in a belt you wear, but it has to line up really close to communicate or it quits. We ended up doing it in bed as trying to wear during the day was hard to keep it connected.

As pain relief decreased over time she eventually had it out. Dealing with the charging wasn't worth it.

I believe that your body gets used to the stimulaton and it becomes less effective, kinda like it's healing itself from the changes you made to it. It sees it as a foreign body and counteracts it. Just seems like the pain relief decrease over time is somewhat common. Again just my thoughts
