What is one product that works unbelievably well for you?

I have back issues. I almost can’t do anything without jacking up my sciatic nerve. Can’t stand too long, can’t bend over, can’t stretch. If I do I have to hobble back to my recliner to rest it.
It’s really taken a toll on my life.
Well, my oldest daughter, who is on disability, for her severe back issues, told me about this wrap and gave hers to me to try on.
It is a wrap you wear just below the knee. There is a rounded disk, about the size of a silver dollar sewn into the wrap. You position the disk outside of your calf, just under the knee, so it presses on the sciatic nerve.
I was super sceptical because she’s all in to essential oils and things that I find silly, and the wrap seemed too much like accupuncture. But I put it on…and literally gasped. The pain was gone instantly. It’s like freakin’ magic. I was scrubbing floors, taking walks, cleaning house, none of which I could do much of before.

Have you ever had anything work so well for you?
