hi all, i am having these weird attacks that start with my legs stretching then my body feels like electrical shocks are zapping different parts and i jerk all over. it feels like fight or flight x 100. i panic all through this but can't tell if the panic started it or if i'm panicing because of it. when it is over i am in so much pain all over that i just can't hardly stand it. i wear a fentanyl patch and take xanax and epitol. i take many supplements also. anyone here ever gone through these hellish attacks?
