Unexplained neuropathy

Hi Everyone,
I wanted to see if anyone has symptoms like me or might know what I have. I have had electric shock pain in my left shoulder my whole life. It would happen once a year usually and be dibilitating but because it only lasts a few seconds I never had it looked into.
Last August I had a week of severe shocks and after lots of dr visits and seeing a neurologist was placed on lyrica which I take each day.
I now seem to have two or three weeks of absolutely no pain and then I will have a night of severe level 10 pain. The shocks only last a few seconds but happen every 10 or so minutes for a 12 hour period usually at night. This week I had the electric shock pain in my shoulder and also my lower back.
I have researched a lot and can't seem to find anyone with these symptoms and would love to try to find a way to explain what I have and see what I can do to help.
Thanks for reading:-)
