The sciatic nerveis the body's longest nerve.1It originates in your lower back and runs behind your legs. Compression or irritation of the nerve root in thelumbar spineor the nerve anywhere along its path can cause sciatic nerve pain and other symptoms in the lower body.2 This may be du...
buttocks, legs, and feet on both sides.Bone spursand spinal stenosis (narrowing) can also put pressure on the sciatic nerve in the lower back. When that happens, it can cause a lot of problems all the way down the nerve.
It is a relatively common condition that, while bothersome, is not of great concern in most cases. Conservative treatments typically offer relief. In some situations, however, sciatic pain is an early sign of a serious nerve or spine problem that may require intervention. Symptoms of Sciatica Sc...

Piriformis syndrome:Piriformis syndromecan cause the sciatic nerve to become trapped deep in the buttock by the piriformis muscle. The symptoms of piriformis syndrome are the same as those of sciatica. Sciatica can also be caused by the nerves being pinched byosteoarthritisand fractures due toosteopo...
What are the symptoms of sciatica? The most common symptom associated with sciatica is pain that radiates along the path of the sciatic nerve, from the lower back and down one leg; however, symptoms can vary widely depending on where the sciatic nerve is affected. Some may experience a mild...
Schwannomas are tumors with slowly progressive symptoms, more often painful than associated with neurologic deficits. Involvement of the sciatic nerve mimics chronic sciatic pain due to a herniated disk. If there is no lumbar pain and lumbar MRI is normal, the sciatic nerve must be clinically and...
Satellite glial cells (SGCs) in the dorsal root ganglia (DRG) play a pivotal role in the formation of neuropathic pain (NP). Sciatic nerve stimulation (SNS) neuromodulation was reported to alleviate NP and reduce neuroinflammation. However, the mechanisms underlying SNS in the DRG remain unclear...
sciatica. Similarly, a fracture in the lower spine, as well as spinal tumors, can cause sciatic nerve compression and result in pain and other sciatica symptoms. In rare cases, cancer may spread to the spine, inflaming the cauda equina nerve roots and causing symptoms similar to disc-related...
The sensory symptoms are co-morbid with behavioural disabilities, such as insomnia and depression. To study chronic neuropathic pain several animal models mimicking peripheral nerve injury have been developed, one of the most widely used is Bennett and Xie's (1988) unilateral sciatic nerve chronic ...
