How can i treat sciatica naturally, especially at the stage of increasing numbness and tingling of leg?

Sciatica: Sciatica often improves after several weeks but usually there is associated aching pain. You may have a disk pressing on a nerve root exiting your spine. See a neurologist or neurosurgeon if symptoms persist or worsen and the appropriate tests and treatment will be ordered. Until then avoid heavy lifting or prolonged standing and , if you can take nsaids like advil, (ibuprofen) they may help.

Stretching, exercise: You will likely need instruction by a physical therapist to learn the mckenzie protocol, but quite worthwhile to pursue. Also, there is a good chance that your protruded or ruptured disc might desiccate and shrink over a 6-8 month time period. But if increased weakness, muscle atrophy, uncontrolled pain, or problems with bladder, surgery is vital. Good luck.

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.
