How long should electric shocks last in sciatica?

See below: Sciatica occurs when one of the nerves leaving the back gets compressed as it leaves the spine and travels down the leg. Compression may occur due to degenerative/bulging discs or arthritic bone spurs contacting the nerve. This may improve on it's own, if these symptoms last longer than 2 weeks or get progressively worse see your physician.

4-6 weeks: Initially the symptoms last 4-6 weeks and if your body heals like it supposed to then pain relief starts. However disc herniations which are the cause of majority of sciatica symptoms last for 6-9 months and therefore people can have pain during that time as well. If not better after 6 weeks see a spine specialist to evaluate this further.
