Sciatica vs. Sciatic Nerve Pain
Do you suffer from low back or gluteal pain and wonder if its sciatica? It could be, but it can also be sciatic nerve pain.
Sciatica is a type or symptom of lumbar radiculopathy and it is caused when a nerve root from L4-S1 is compressed by either a herniated disk, bulging disk or disk degeneration; as these are the most common causes. When one of these lumbar nerve roots becomes compressed, it triggers symptoms such as paresthesia (tingling, pins and needles or tightness) sharp pain, numbness and/or weakness that radiates from the low back to the thigh and down to the knee and ankle.
When a person is experiencing pain that initiates in the lateral side of the gluteal region and it does not radiate down a lower extremity can be due to sciatic nerve pain caused by inflammation and pain from the piriformis muscle which Is located above the junction of sciatic nerve roots through the greater sciatic foramen which is an opening in the pelvic bone. When the piriformis becomes aggravated, it can put pressure on the sciatic nerve, causing sciatic nerve pain, NOT sciatica.
Another type of sciatic nerve pain that gets confused with sciatica is SI or Sacroiliac Joint pain. The SI joint is located in the pelvis connecting both the pelvic and sacrum bones. Pain is felt in your sacrum region (the lowest part of your spine between your low back and tailbone) and pelvic bone and it can be described as sharp with movement such as walking, twisting or turning and it’s a localized pain. SI joint pain can also radiate to the gluteal area and down the posterior thigh but it does not radiate down the entire lower extremity. Sacroiliac joint can be aggravated by twisting, turning or moving the wrong way, heavy lifting such as squats using excessive amount of weight, etc…
