I have this and the "root cause" seems to be lower back for me. I do cat/cow/child/cobra yoga, clamshell stretches, leg edema massage, pumping of feet and hamstring stretches - on the bed, before sleep. I do THC/CBD tincture under my tongue. I mix my own and try to buy the indica strain. The CBD tincture I buy is 600mg and the THC is 600. Roughly 2:1 of CBD/THC, about an hour before bed. I have a sleep disturbance going on also, and Percoset helps with that. Scar tissue in my knee is contributory; so a good brand cbd ointment (I use Happy Salve), or lidocaine patch there. I think the THC helps the activation of cbd and, you can experiment to see what works; keep adding a little more. For breakthrough, I take 1/2 THC/CBD gummy an hour or so later, as well as cold/heat and magnesium. Leafly is a good website. It is a misery, for sure but at least I am mostly sleeping well. Sleep doctor appointment in November.
