Personally, I would try every possible non-invasive option first. Implants are a bell that can't be unrung with RSD at times... Is that 80% success rate in RSD patients or regular patients?

Has your daughter gone through an inpatient RSD program for children? As asked above--tried Ketamine? HBOT? Changed her diet? tCDS (under the care of a doc.) Etc. Etc. Etc.

It might make her better, but what if it makes her worse? There are many posting about horrific spread happening from implants such as SCS, as well as those that have had great improvement. The risks seem too great to me personally, to undergo, and I would be even more conservative in my risk taking in regards to my child.

Good luck!
