I used to experience this in my head and neck. My osteopath told me it was from tight muscles putting tension and pressure on the nerves until they release which causes the electric shock feeling. I'm not sure if that helps

My Chiropractor thinks the same as Lisa (above). I have also found that my TENS machine helps when I'm up and out of bed, it seems to "fool" your body to direct it's attention to the part where the pads are?.. I also found some links for PMR (progressive muscle relaxation) meditation which helps when I'm in bed and seems to reduce these pain "shocks"

That's one of the feelings that I've only experienced once so I'm not sure if I really have fibromyalgia but I definitely have lots of soft tissue and muscular tightness knots... I am constantly stretching to feel like normal . When I drive I have to lay back to stretch out my back , I have neck issues, too many injuries , and severe fatigue at times from Hardly doing anything Etc problems. The only time strangely enough that I've ever experienced that zap electrical thing was when I drank a Coke about 15 years ago. I had not drank a Coca-Cola in a long time. That night at midnight I sat up in the bed and an electric current was coming out of my head. It was the strangest thing. I felt like I was a lightning rod ...
I know it was from the the cola. I am mentioning this because sometimes people don't realize that certain things they are putting in their body are contributing . In my case it was clearly the coke. I have not touched Coke since and have not experienced the electric current. I cannot take medicine like amitriptyline and others which I've tried because I will get zaps in the head from the medication.

Hi Stephanie

This is one of my Fibro symptoms that I really struggle with, it’s sooo awful to deal with! I find it’s worse when Iam Trying to relax. I litterally can’t keep still because of the pains. I do not take medications due to the side terrible side affects. I find yoga and meditation to help ease the pain. Took me years to get used to my new normal and it just keeps changing. I’ve learnt to ride the rouge waves of pain ❤️‍🔥

Sorry, it is really bad for you right now. We are here if you need to vent. Don't beat yourself up during this time. Take it slow and try not to push yourself too hard, because it will not help it. You can try soaking in a warm bath, and ice on the initial flare-up spot. Cyclobenzaprine helps the muscles relax so they do not hurt as much from the shocks, some find it helps with shocks, but it is not for it so it's okay if it does not work on yours. Hope something helps find you a little relief and comfort.

It will not always last this bad, but I will not lie and say they go away.
