Common Causes of Sciatica

What is sciatica?

Sciatica is a term commonly used to describe pain, weakness, numbness, or tingling that radiates down the back of the leg. These symptoms can be debilitating for some and contribute to difficulty performing daily activities.

Where does it come from?

There are 4 common causes of sciatica:

  1. Disc Herniation – Pressure on the sciatic nerve can occur from the protrusion of a disc in the lumbar spine. This pressure can cause pain to travel through the pathway of the sciatic nerve down the leg.
  2. Spinal Stenosis – Narrowing of the space where the nerve roots exit the spinal canal can also cause pressure on the nerve.
  3. Piriformis Syndrome – The piriformis is a muscle deep in your gluteal region that the sciatic nerve runs underneath and sometimes through. Tightness or spasm of this muscle can cause pressure on the nerve that sends pain down the leg.
  4. Referred Pain from Trigger Points – Trigger points are tight knots in muscles that can cause local or referred pain. Trigger points found in the gluteal muscles can cause referred pain that is felt down the leg and is similar to sciatic nerve pain.

How can PT help?

 A physical therapist is trained to evaluate your symptoms and do a thorough assessment to determine what may be causing them. The aim of treatment is to restore your range of motion, increase your flexibility, increase strength and stability, decrease trigger point formation, and improve your functional mobility. Treatment plans are individualized and are determined based on the causes of your symptoms and your specific presentation. If you are suffering from sciatica-related symptoms, call Harbor Physical Therapy to help eliminate your pain and prevent it from reoccurring.
