The 5 Trigger Points of Sciatica

Sciatica is a symptom, or group of symptoms, caused by any number of conditions which compress the sciatic nerve. The main symptom of sciatica is pain radiating from the lower back or buttocks, down the back of the thigh. Pain may travel as far as the calf muscles. There may also be associated tingling, numbness or weakness.

There are numerous conditions which may cause sciatic pain. These include a lumbar disc herniation (also known as a slipped disc, or herniated disc); spinal canal stenosis; sacroiliac joint dysfunction and piriformis syndrome.

Sciatic pain can also be caused by trigger points (T.P's) within the gluteal (buttock) muscles. This is sometimes referred to as myofascial pain.

A trigger point is also sometimes known as a muscle knot. They are hypersensitive points within a tight band of muscle which often refer pain throughout the area they are found in. T.P's can be felt as small, tender lumps within a muscle, which when compressed, often cause pain which may radiate elsewhere and a twitch response in the muscle.

What are the 5 trigger points of Sciatica?

Sciatic pain radiating into the hamstrings can be caused by trigger points found in the buttock muscles.

Sciatica caused by T.P's develops gradually with no specific point of injury; there may be a cramping or tight sensation in the buttocks or hamstrings and tenderness when pressing these muscles. There is not usually any lower back pain, walking and even running may be pain free and strength is rarely affected.

The 5 T.P's which most commonly cause sciatic pain are described here:

1, 2 & 3: Gluteus Medius

Gluteus medius is one of the three Gluteal muscles ('glutes') which form each buttock. They are responsible for extending, abducting and laterally rotating the hip joint.

Gluteus medius is found just below the https://saludaio.com/dolor-cresta-iliaca/"> cresta ilíaca. There are three common T.P's in this muscle which can refer pain into the posterior thigh. They are located at the origin of the muscle, all three in a row, just below the iliac crest.

4: Tensor Fascia Latae

TFL (as it is shortened to) is a small muscle found on the outer hip. It attaches to the front of the iliac crest and descends downwards to converge with the IT band on the outer thigh.

A trigger point can often be found in the superior half of the muscle, which radiates pain inferiorly, down the IT band and lateral hamstrings.

5: Piriformis

The Piriformis muscle is a small muscle found deep within the centre of the buttock. It originates from the Sacrum and crosses horizontally to the head of the Femur (thigh bone).

It is strongly associated with https://www.webmd.com/back-pain/ss/slideshow-visual-guide-to-sciatica">sciatica as a condition called Piriformis syndrome can also cause sciatic symptoms. However, this is an actual compression of the nerve caused by muscle tension or an anatomical variation where the nerve passes through the Piriformis muscle (rather than behind it). This occurs in around 10% of the population.
