How to prevent other sciatica attack ( i mean what is best to do,when i get through this one)any tips?

See details: Do you back exercises everyday. Lift with you legs and not your back.

Core Exercises: Typically core strengthening exercises are the best to help relieve pressure and forces in the spine. I would try and google some or look them up on youtube to see descriptions. If you can do them yourself, wonderful otherwise ask your doctor to get a referral to a good physical therapist for further assistance.
