Any one experience this symptom?

I recently hurt my sciatic and can sometimes feel it up and down my right leg, but there times when I feel a strange feeling in my lower stomach, groin area - almost like a very low voltage feeling going through my body.  Maybe a tingling sensation, but more of sudden spasm.  This comes and goes, and usually goes to a different area on different days, but for the last week I've experienced it pretty much.  Anyone else?
