- Sciatica (or sciatic neuritis) is a set of symptoms including pain that caused by general compression and/or irritation of one of five spinal nerve roots that give rise to each sciatic nerve or by compression or irritation of the left or right or both sciatic nerves. The pain is felt in the lower back, buttock, and/or various parts of the leg and foot. It can be acute, sub acute or chronic in duration. In addition to pain, which is sometimes severe, there may be numbness, muscular weakness, pins and needles or tingling and difficulty in moving or controlling the leg. Typically, the symptoms are only felt on one side of the body. Pain can be severe in prolong exposure to cold weather.
- Sciatica is generally caused by the compression of lumbar nerves L4 or L5 or sacral nerves S1, S2 or S3, or by compression of the sciatic nerve itself. Spinal disc herniation, Spinal Stenosis, Piriformis syndrome, Trigger points, Pregnancy, Habits are causative factors of sciatica.
Sciatica pain can vary widely. It may feel like a mild tingling, dull ache, or a burning sensation. In some cases, the pain is severe enough to make a person unable to move. The pain most often occurs on one side. Some people have sharp pain in one part of the leg or hip and numbness in other parts. The sensations may also be felt on the back of the calf or on the sole of the foot. The affected leg may feel weak. The pain often starts slowly. Sciatica pain may get worse:
- After standing or sitting
- At night
- When sneezing, coughing, or laughing
- When bending backwards or walking more than a few yards, especially if caused by Spinal Stenosis
- Partial or complete loss of leg movement
- Partial or complete loss of sensation in the leg
- Recurrent or unnoticed injury to the leg
MRI Scan may be prescribed to assess the precise physiological status of the spine in the affected region.
