@johnbluffside Hi John - This was a new term for me, so my caffeine-fueled brain had to immediately jump into research mode. Especially because I seem to be experiencing a pain flare this week, and can't sleep much.

For curious minds, the Jovi Patch is advertised as a resusable patch which:
"Jovi relief products contain patented technology sandwiched between two layers of medical grade material, designed to work with your body's natural electrical signals to reduce the impact of pain. It feels like magic, but it's science!" It has a companion in the marketplace called the Kailo Patch.

Both of these devices have been around for several years. claim to be "seeking FDA Approval", yet have published ZERO controlled, independent research studies on their effectiveness. All of the sites promoting the patch are of the "testimonial" variety.

Here are short reviews from two respected publishers of medical information:

https://www.mcgill.ca/oss/article/medical-critical-thinking-health-and-nutrition/sticky-pain-patchs-science-hits-sticky-patch
My takeaway? Probably in the "snake oil cure" category. I have better places to spend my money.

Have you tried targeted Physical Therapy for your sciatic pain?
