Know About Sciatica: The term “sciatica” refers to leg nerve discomfort caused by irritation and/or compression of the sciatic nerve. Sciatica is a condition that begins in the lower back, extends deep into the buttocks, and continues down the leg.
What Does Sciatica Feel Like?
Symptoms of sciatica are most commonly observed along the path of the large sciatic nerve. Sciatica is characterized by one or more of the following criteria:
- Pain. Sciatica pain is characterized by a persistent burning feeling or a shooting pain that radiates down the front or back of the thigh, leg, and/or foot from the lower back or buttock.
- Numbness. Numbness in the back of the leg may convoy sciatica pain. Tingling and/or weakness can present at times.
- One-sided symptoms: Sciatica usually affects only one leg. A heaviness in the afflicted limb is a common symptom of the illness. Both legs may be injured at the same time in rare cases.
- Posture induced symptoms. While sitting, trying to stand up, bending the spine forward, twisting the spine, lying down, and/or coughing, sciatica symptoms may become worse. Walking or using a hot pack to the back of the pelvis might help ease discomfort.
It’s vital to realize that sciatica is not the same as lower back pain or radiating leg pain. Sciatica is a term used to describe discomfort that stems from the sciatic nerve.
Sciatica Is the Symptom of an Fundamental Medical Condition
Sciatica is a phrase that describes a group of symptoms induced by a medical disease; it is not a medical diagnosis.
Sciatica can be caused by a variety of medical problems.
Sciatica can be caused by tumors, blood clots, or other problems in the lower spine.
The phrases lumbar radiculopathy or radicular pain, in addition to the terminologies that define the underlying diseases that produce sciatica, can be used interchangeably with the term sciatica.
The Sciatic Nerve and Sciatica
The sciatic nerve is the body’s biggest single nerve, created by the joining of five nerve roots in the lumbar and sacral spine. The right and left sciatic nerves, which feed the corresponding lower limb, are the two sciatic nerves in the body.
The sciatic nerve has a number of anatomical properties, including:
- Origin. The sciatic nerve is generated by the merger of spinal nerve roots from L4 to S3.3, starting at the level of spinal segment L4. The growing nerve roots merge to form a single sciatic nerve, which is big and thick, with a diameter of up to 2cm.
- Path. The sciatic nerve departs the pelvis through the larger sciatic foramen, which is located under the piriformis muscle, when its separate contributions have ended. The nerve then travels down the back of the thigh, through the leg, and into the foot.
- Branches. Behind the knee, the sciatic nerve divides into two main divisions: the tibial nerve and the common peroneal nerve. The tibial nerve runs down the back of the leg and nourishes the sole of the foot. The front of the leg and foot are supplied by the common peroneal nerve.
Near the sciatic foramen, the sciatic nerve may split into two nerves, which then join again into a single nerve.
The precise symptoms of sciatica are primarily determined on which nerve root is pinched. 3 An L5 nerve impingement, for example, might produce discomfort in the back of the leg as well as difficulty in elevating the big toe and ankle.
The Course of Sciatica
Sciatica is often not caused by a single event or injury, but rather develops over time. Sciatica affects 10% to 40% of the population, with the majority of cases occurring in those over the age of 40.
Sciatica is widespread in some occupations that require physically demanding postures, such as machine workers or truck drivers. Sciatica is a condition that affects patients who routinely bend their spine forward or laterally, or raise their arms above shoulder level.
With nonsurgical sciatica treatments, the great majority of patients who suffer from sciatica get well in 4 to 6 weeks. Recovery may take longer if there are substantial neurological problems. However, up to 33% of persons may experience chronic symptoms for up to a year. When there is considerable nerve compression and symptoms are becoming worse, surgery may be necessary.
