Is it sciatica if i only feel electrical shocks a few times a day only in my lower back and bum? thanks for the help!

Possible: But if you only experience minor symptoms, unlikely that you have a profound problem. Alternatively, could be a piriformis syndrome, or even an issue with sacroiliac joints. A bit of prevention now may protect you against full-blown issues. Consider a visit to an osteopathic specialist or a physiatrist.

Usually sciatica: Will radiate down the posterior thigh or to legs.- although I have seen cases that started out only in the "bum".

Typical Nerve: Nerves do all sorts of things when irritated so it is common to feel the vibration sensation. Usually this will go away on its own. If you are worried then see your doctor for further evaluation.
