Sciatica is the term used to describe nerve symptoms—most commonly pain—that travels down the thigh and/or leg. Sciatica, on its own, does not indicate lower back pain.
Sciatica is the name for pain patterns caused by irritation of the sciatic nerve—most notably in the back of the thigh and leg. The sciatic nerve is most often irritated by the piriformis muscle, a hip muscle that exits the pelvis through the same opening as the sciatic nerve.
For gamers, sciatica usually occurs due to prolonged sitting and is exacerbated by poor posture. Refer to our guide for gamer posture to reduce your risk for the piriformis muscle causing sciatica.
Symptoms of sciatica may also stem from irritation of some nerves at the spinal level; however, this page will focus primarily on true sciatica, or direct impingement of the sciatic nerve in the pelvis or thigh.
It’s important to know some basic anatomy of the lumbar spine and pelvis to understand sciatica.
To begin, the sciatic nerve is the largest nerve in the human body. It is a collection of lumbar & sacral nerve roots that provides motor control for the majority of the thigh, leg, and foot.
Through its terminal branches, the sciatic nerve also supplies touch sensation for the lower leg and foot.
For each bone in your spine, there is an associated nerve root that corresponds with an area of the body. In the lower back, nerve roots L4, L5, S1, S2, and S3* combine to form the sciatic nerve.
* The letters and numbers refer to the spinal region and segment (L = lumbar, S = sacrum); there are 5 lumbar bones & nerve roots and the sacrum bone has 4 nerve roots
Nerve roots L4 through S3 combine to form the sciatic nerve within the pelvis. The sciatic nerve then exits into the gluteal region through an opening in the pelvis called the sciatic notch.
In the thigh, innervation of the sciatic nerve is motor only; it does not include cutaneous (skin sensation) innervation. The muscles of the sciatic nerve are the hip external rotator muscles and the muscles in the posterior compartment of the thigh:
Just above the knee, the sciatic nerve splits into 2 branches: the common peroneal nerve and the tibial nerve. These nerve branches innervate the muscles in the lower leg, ankle, and foot.
These nerve branches also include cutaneous innervation to the lower leg and foot with the exception of the medial (inner) portion.
Sciatica occurs when there is compression or irritation of the sciatic nerve. The compression or irritation may be caused by:
Since the sciatic nerve contains nerve roots L4 through S3, the possible affected area is quite large:
In these regions, sciatica will present as one or more of the following symptoms:
Sciatica will not present as pain, numbness, tingling, or weakness in the inner portion of the thigh, lower leg, or foot. These symptoms are instead associated with femoral nerve impingement or nerve root irritation T12 through L3.
Note: if you experience the above-listed symptoms along with swelling of the leg, ankle, or foot, paleness or blue color, and/or cool or cold sensation, these are signs of a more serious condition. You should consult your doctor or visit the emergency room if you experience these symptoms.
Sciatica is more likely to occur in people who sit for prolonged periods of time, especially if the seated posture is awkward or off balance. Prolonged sitting or awkward position may cause irritation in two ways:
The most common mechanisms of injury for sciatica are direct compression of the sciatic nerve and poor and/or prolonged static position.
Body position: check out our posture education page to check your seated posture and reduce the risk of developing sciatica.
Take breaks: for every half hour you’re sitting, you should stand up and walk around for 5 minutes!
To effectively resolve sciatica, it is important to first identify and correct the initial cause. For example, if you’re sitting too frequently without taking breaks or sitting awkwardly, protocols may be ineffective because of the constant exacerbation.
In practice, the following treatments are effective for the treatment of piriformis syndrome:
Esports Healthcare will also utilize the Hypervolt+ percussion tool for treatment of piriformis syndrome.
To your tolerance, the Hypervolt+ can be used to massage the the piriformis muscle in the gluteal region. Please note, this treatment may be painful to endure.
Esports Healthcare utilizes the Hypervolt+ for treatment, and we wanted you to have access to this tool, as well. So, we’ve partnered with Hyperice to provide a 15% discount on ALL Hyperice products!
It is also important to eat an anti-inflammatory diet and/or include anti-inflammatory supplements in your diet to prevent chronic, systemic inflammation that may worsen nerve compression in the gluteal region.
Following resolution, continuation of these protocols allows for prevention of this condition from reoccurring.
