Where is the sciatic neuralgia?

summary

Sciatica is a common symptom, it refers to the sciatic nerve and the distribution area, a comprehensive manifestation of pain, mostly because of the sciatic nerve site and the surrounding lesions, because it is nerve stimulation leading to compression and damage, causing abnormal pain in patients, at this time should be timely corresponding examination, For example, imaging examination, electrophysiological examination and so on. Let's share my experience with you.

Where is the sciatic neuralgia?

(1) The pain is mainly confined to the sciatic nerve distribution area, the back of thigh, the posterolateral side of leg and foot. Patients with severe pain can show a unique posture; Waist flexion, knee flexion, toe landing. If the lesion is located in the nerve root, the pain will be aggravated when the pressure in the spinal canal increases (cough, exertion)（ 2) The degree of muscle weakness may vary greatly according to the cause of disease, the location of lesion and the degree of damage（ 3) There may or may not be tenderness of the sciatic nerve trunk at the sciatic notch.

(4) The presence of sciatic nerve stretch sign, Lasegue sign and its allele sign is often parallel to the severity of pain. The sign of sciatic nerve root or nerve trunk disappeared under local anesthesia（ 5) Achilles tendon reflex decreased or disappeared, and knee reflex increased due to stimulation（ 6) There may be hypoesthesia or disappearance of various senses in the area of sciatic nerve innervation, including hypoesthesia of lateral malleolus, or very mild sensory disturbance.

1. Imaging examination plays an important role, including X-ray film of lumbosacral vertebrae and sacroiliac joint, spinal MRI, myelography and CT. In addition to clinical physical diagnosis of pelvic cavity, CT or MRI of pelvic cavity can be used. 2. Electrophysiological examination (1) EMG of paravertebral muscles can help to identify the root sciatica and distal lesions.

matters needing attention

In daily life, eat more fruits and vegetables, keep optimistic mood, pay attention not to fatigue, pay attention to the recovery of the body, in addition, if there are any symptoms should go to the hospital for examination, and corresponding treatment, these are to actively do.
