Sciatica pain which i get sledom?

Sciatica: Sciatica is a neuropathic pain due to nerve compression. The symptoms can vary. I recommend you see a doctor for evaluation.

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.
