When experiencing sciatic nerve pain, it is important to first determine the cause. It may be due to a herniated disc compressing the nerve root, or it could be caused by piriformis syndrome. If the pain is caused by a herniated disc and it is the patient's first occurrence, a CT scan can be done. If the herniation is mild, conservative treatment may be chosen, such as wearing a lumbar support and performing some traction. Patients can also actively exercise their back muscles to alleviate the sciatic nerve pain. Additionally, it is recommended to sleep on a firm bed and spend more time lying down than sitting. If the herniation is severe, has been prolonged, or it recurs frequently, it is advised to seek professional treatment in orthopedics. If the pain is due to piriformis syndrome, a visit to a pain management clinic is suggested for symptomatic relief and pain alleviation.

What to check for sciatica

Sciatica is divided into primary sciatica and secondary sciatica. Secondary sciatica is very common and is mainly due to diseases of the spinal canal, including herniated lumbar discs, lumbar spinal stenosis, or spinal tumors compressing the spinal cord and nerve roots. Another condition is piriformis syndrome, where the sciatic nerve exits; if there is narrowing here, it can also cause sciatica. Therefore, clinically, one starts with secondary sciatica, conducting either a lumbar spine CT scan or an MRI, which can basically clarify the location causing the compression. Another type is called primary sciatica, which is caused by inflammation of the sciatic nerve, and is an internal medicine disease, not an orthopedic disease. This requires an electromyography (EMG). After completing the EMG, the diagnosis can generally be made based on the injured muscle or the muscle with abnormal electromotor conduction. Thus, the routine examinations for sciatica are X-rays, CT, MRI, and the non-routine examination is the EMG.

What causes sciatica?

The causes of sciatica generally fall into two categories. The first is primary sciatica, which is usually caused by inflammation of the sciatic nerve and is relatively rare in clinical practice. The second category is secondary sciatica, which occurs when the tissues and structures around the sciatic nerve undergo pathological changes, leading to stimulation and compression of the sciatic nerve, thus causing secondary sciatica. The majority of secondary sciatica cases are associated with lumbar spine disorders, such as lumbar disc herniation, tumors in the lumbar spinal canal, or degenerative joint disease of the lumbar spine, as well as sacroiliitis. A hospital examination is necessary to make a definitive diagnosis.

Does sciatica cause numbness in the legs?

Sciatica can cause sensory abnormalities in one lower limb and even lead to muscle weakness. It can also cause numbness and sensory abnormalities on the dorsum or sole of the foot. However, foot numbness should first exclude causes like exposure to cold or poor blood circulation in the lower limbs. After excluding other causes of foot numbness, it can be diagnosed as sciatica-induced symptoms such as foot numbness. At this time, it is advisable to actively nourish the nerves and avoid certain postures that may aggravate sciatica. Additionally, sciatica can also be caused by lumbar disc herniation, or simply by the local compression of the sciatic nerve in its course.

Which department should I register for sciatica?

Sciatica is divided into primary and secondary types. Primary sciatica is caused by inflammation of the sciatic nerve itself, thus one should visit the Department of Neurology. Secondary sciatica is more common and usually stems from spinal conditions, so initially one should visit the Department of Spinal Surgery. Alternatively, one can visit the Department of Orthopedics, which deals with broader orthopedic issues. If experiencing severe acute pain, a visit to the Pain Management Department can provide rapid and effective pain relief. For frequent episodes of sciatica and interest in rehabilitation, the Rehabilitation Department can be considered. Additionally, traditional Chinese medicine has unique approaches to treating sciatica, so visiting the Department of Traditional Chinese Medicine to try treatments with Chinese herbs and methods is also an option.

How to treat sciatica

Sciatica typically has two treatment methods. One is non-surgical treatment, which is currently the first and most commonly used approach. The first step is general treatment, meaning that once symptoms of sciatica occur, one should rest on a hard board bed. Second, one can combine this with some heat applications to the lumbar area, physical therapy, and acupuncture; all of these are options. The third is traction therapy, which is very effective for discogenic sciatica, as it can reduce the pressure on the intervertebral disc, thereby increasing the volume of the spinal canal and enlarging the area of the intervertebral foramen, thus reducing stimulation to the nerve. Fourth, one can consider undergoing sacral canal injections, or using papain or collagenase for chemical dissolution of the nucleus pulposus, which usually can also achieve a good effect. The fifth point is that when symptoms are reduced, one should start exercising the lumbar and back muscles to increase their strength and enhance the stability of the lumbar spine, thereby ensuring the stability of the intervertebral disc. It should be mentioned that massage and manipulation are quite effective for herniation of the disc nucleus pulposus, but if there is already obvious osteophyte formation, narrowing of the intervertebral space, or disorder of the facet joints, or even lumbar spinal stenosis, then massage and manipulation are not recommended. If the aforementioned treatments prove ineffective, the condition does not relieve or even worsens, or if there is central herniation of the lumbar disc, or if the patient shows significant cauda equina nerve stimulation symptoms, then surgical treatment is required.
