What is Sciatica?

Sciatica is a pain in the lower extremity resulting from irritation of the sciatic nerve. The pain of sciatica is typically felt from the low-back (lumbar area) to behind the thigh and can radiate down below the knee. Sciatica is specific pain that is a direct result of sciatic nerve or sciatic nerve root pathology. The term sciatica is limited to the pain and irritation in nerve roots from L1 to L4 and may also involve related areas. Many times patients and clinicians use sciatica to describe any pain arising from the lower back and radiating down to the leg.

Synonyms for sciatica pain are lumbosacral radicular syndrome, ischias, nerve root pain, and nerve root entrapment. The various causes of sciatica include spine disc herniation, spinal stenosis, pregnancy, piriformis syndrome, osteoarthritis, spondylosis and spondylolisthesis. In maximum cases, sciatica is caused by a herniated disc with nerve root compression, but lumbar canal or foraminal stenosis and (less often) tumors or cysts are other possible causes.

There are a set of neurological symptoms, such as pain (intense pain in the buttock), lumbosacral radicular leg pain, numbness, muscular weakness, gait dysfunction, sensory impairment, and sensory disturbance, hot and cold or tingling or burning sensations in the legs, reflex impairment, and others.
Sciatica involves a pain that is released down the back of the leg, sometimes as far as the foot and toes.

The pain is the result of a problem with the large sciatic nerve. Pain that travels down the leg in this way is not always generated by the sciatic nerve and structures, such as spinal joints and lumbar discs, which can also cause pain to travel down the leg.

Patients who have sciatica are best aided by a treatment plan that is individualized based on the patient’s symptoms, diagnosis, and response to various treatments. Many cases of sciatica go away within a few weeks using conservative treatment methods.

However, this is not the case for all patients. For some, sciatica can last much longer, even for several months. Currently, the market holds no approved therapy to treat Sciatica. The market of Sciatica holds treatment options that are supportive in nature, such as conservative (nonsurgical) and surgical methods. Conservative treatment of sciatica further includes physical therapy, behavioral therapies, or pharmacological therapies.
