Typically, electrical sensations/numbing/burning/tingling are associated with nerve involvement.

Lyrica works for me because I have very bad Neuropathy in both my feet. At times it feels like each one is a block of ice with burning needles of pain that stabs me. At night I can"t sleep unless I have the Lyrica , or Gabapentin 600mg BID, to take away the intense pain. This may not work for everyone but for some it does help.

I get them in my head like electic shockes

Hi I had alot of it before my neck surgery. Now not so much. It is caused either by neuropathy or stenosis. Mine is caused stenosis and neuropathy. I have severe cases of both.

I used to only get them in my hands, for the most part, now i can experience them anywhere, varying to shooting electrical shocks to what feels like a hot sting.
