Surface location of sciatic nerve

It is generally believed that a medical image examination is needed to determine whether it is the sciatic nerve surface. In other words, once the patient feels that he may have this disease, it is best to go to the hospital as soon as possible to be examined by a professional doctor to avoid missing the best treatment time due to untimely treatment. In addition, the doctor told us that once this happens, it is best to quit smoking immediately. Let’s learn about the common sense issues related to the surface location of the sciatic nerve below.

The surface location of sciatica should be determined based on the results of medical imaging examinations. Patients should go to a regular hospital for examination and receive treatment under the doctor's diagnosis without delay.

People with sciatica should stop smoking. First, the nicotine in the cigarette is a harmful substance that can cause small blood vessels to contract and spasm, reducing blood supply. Second, the carbon monoxide contained in the cigarette can replace the oxygen in the red blood cells, further reducing the already insufficient nutrients in the sciatic nerve trunk, or worsening the condition. Clinical observations have found that the proportion of smokers in patients with lumbar disc herniation is relatively high, and their symptoms are often more severe. Lumbar disc herniation may be complicated by sciatic nerve necrosis. Therefore, patients can quit smoking while undergoing treatment to promote the recovery period of sciatica.

There are many causes of sciatica. The sciatica in the vast majority of patients is secondary to the stimulation, compression and damage to the sciatic nerve caused by lesions in the local sciatic nerve and surrounding structures, which is called secondary sciatica; a few are primary, namely sciatica. The pain is mainly limited to the sciatic nerve distribution area, the posterior thigh, the posterolateral side of the calf and the foot. Patients with severe pain may adopt a unique posture: bending their waist, bending their knees and standing on their toes. If the lesion is located at the nerve root, the pain will worsen when the pressure in the spinal canal increases (coughing, exerting force).

In short, this article has provided some introduction to sciatica. If you are still confused after reading the above introduction, you can consult a professional doctor for details.
