Sciatica — Overview, Symptoms, Treatments, and Other Resources.
Information on Sciatica from the American Academy of Orthopedic Surgeons.
If you suddenly start feeling pain in your lower back or hip that radiates to the back of your thigh and into your leg, you may have a protruding (herniated) disk in your spinal column that is pressing on the roots of the sciatic nerve. This condition is known as sciatica. Read more at the American Academy of Orthopedic Surgeons.

Causes, Symptoms, Exams and Tests, Treatment, Prognosis for Sciatica at the National Library of Medicine
Sciatica occurs when there is pressure or damage to the sciatic nerve. common causes of sciatica include: piriformis syndrome (a pain disorder involving the narrow piriformis muscle in the buttocks), slipped disk, degenerative disk disease, spinal stenosis, pelvic injury or fracture, or tumors. Sciatica pain can vary widely. Because sciatica is a symptom of another medical condition, the underlying cause should be identified and treated. if the cause of the sciatic nerve dysfunction can be identified and successfully treated, full recovery is possible.

Sciatica and Disc Herniation treatment and relief with out drugs or surgery
Adult low back pain.
Back pain assessment should include a subjective pain rating, functional status, patient history including notation of presence or absence of "red flags" and psychosocial indicators, assessment of prior treatment and response, employment status, and clinician's objective assessment. A conservative approach should be first-line treatment. View the major recommendations at the National Guideline Clearinghouse.
Assessment: use of epidural steroid injections to treat radicular lumbosacral pain. Report of the Therapeutics and Technology Assessment Subcommittee of the American Academy of Neurology.
In general, epidural steroid injections for radicular lumbosacral pain have shown no impact on average impairment of function, on need for surgery, or on long-term pain relief beyond 3 months. Their routine use for these indications is not recommended. View the major recommendations at the National Guideline Clearinghouse.

Full Text: Prolonged conservative care versus early surgery in patients with sciatica caused by lumbar disc herniation: two year results of a randomised controlled trial
Early surgery achieved more rapid relief of sciatica than conservative care, but outcomes were similar by one year and these did not change during the second year. Free full text available at Pubmed.
Full Text: Tubular diskectomy vs conventional microdiskectomy for sciatica: a randomized controlled trial.
Context: Conventional microdiskectomy is the most frequently performed surgery for patients with sciatica due to lumbar disk herniation. Transmuscular tubular diskectomy has been introduced to increase the rate of recovery, although evidence is lacking of its efficacy.
Objective: To determine outcomes and time to recovery in patients treated with tubular diskectomy compared with conventional microdiskectomy. Free full text available at Pubmed.
Full Text: Surgery versus prolonged conservative treatment for sciatica.
Lumbar-disk surgery often is performed in patients who have sciatica that does not resolve within 6 weeks, but the optimal timing of surgery is not known. We randomly assigned 283 patients who had had severe sciatica for 6 to 12 weeks to early surgery or to prolonged conservative treatment with surgery if needed. The 1-year outcomes were similar for patients assigned to early surgery and those assigned to conservative treatment with eventual surgery if needed, but the rates of pain relief and of perceived recovery were faster for those assigned to early surgery.

Abstract: The flip test: a reappraisal.
The flip test is commonly performed in patients with sciatica to confirm or otherwise nerve root tension evidenced by a restricted supine straight leg raise (SLR). Passive extension of the knee with the patient in the erect position and the hip flexed is reported to cause a sudden falling or flipping back of the trunk. We consider that the flip test has been substantially misinterpreted in the past. However, it remains a useful check of nerve root tension but only for patients with supine SLRs below 45 degrees . The most reliable response was not a flip but the demonstration of pain on extension of the knee. We would recommend the term "sitting SLR test," as a more accurate and less misleading name.

Full Text: Ruling out piriformis syndrome before diagnosing lumbar radiculopathy.
Piriformis syndrome (PS), a rare cause of sciatica, is usually diagnosed only after excluding all other possibilities. But this principle is being challenged because of the number of patients with PS who have had ineffective lumbar decompressive surgery after positive findings on image study.

Consumers' Guide to Hospitals
Which Hospital Should You Choose (or Avoid)?
What makes the Consumers' Guide to Hospitals so special?
We've got 30 million answers to that question. That's how many hospital records Consumers' CHECKBOOK sifted through to calculate risk-adjusted death rates and adverse-outcome rates, and that's just part of the data used to rate the hospitals. The organization also sent out more than 280,000 questionnaires to physicians in 53 major metropolitan areas in the United States, asking them to rate their local hospitals; checked ratings of the hospitals by surveyed consumers; checked which hospitals were providing recommended tests and procedures for patients with specified medical problems; and more."
