I have had this feeling but mostly at night. I say that it feels like electricity is running through my body. It's not painful; just weird and annoying. I attribute this to my SFN.

I have small fiber neuropathy also and I have mentioned this in another forum (Neuropathy) My specialist says that fibro and SFN can go hand in hand, and I am wondering, out loud, if some of us fibro sufferers also have neuropathy and are attributing some of our symptoms to the wrong DX. I am not trying to dx anyone or make them worry that they may have another problem. But in reading and researching both syndromes, it is thought that fibro isn't just a muscle disease, but also a neurological problem in that the nerves/brain are telling the muscles to hurt (in a simplified definition). Since I have both fibro and SFN, sometimes I can tell which syndrome is affecting me and which one isn't and sometimes both. If my feet are numb and I'm having twitching; it's SFN. If my body hurts all over and I am so fatigued all i want to do is sleep; it's fibro. Of course, it's not that simple. The symptoms overlap. So, don't be too alarmed about the "electricity" running through your body, but do mention it to your rheumy. Also, read all you can by Dr. Daniel Clauw. Our Moderator put up some very valuable information about fibro from him. Excellent! Feel better.
