What things have you been doing at the times you get these shocks, or just prior?
Have you noticed any other new sx, or increases/changes in other sx?
Have you been possibly doing too much recently?
Were you in A/C when these "shocks" occurred?
Are you currently taking anything for neuropathic pain - i.e., Neurontin, Lyrica, Trileptal, Cymbalta, Elavil, amy/nortryptaline (sp) or other of the tricyclics or anti-seizure meds that are are often more effective than pain meds used alone?
More info please!
