What is sciatica

summary

Sciatica is a common phenomenon. If you encounter such a problem, you must pay attention to it. Don't add too much burden to the sciatic nerve, which will lead to the aggravation of the disease. Let's talk about what is sciatica.

What is sciatica

First, sciatica is a syndrome characterized by pain in sciatic nerve pathway and distribution area. The vast majority of cases of sciatica are secondary to the stimulation, compression and damage of the sciatic nerve caused by the lesion of the local and surrounding structures of the sciatic nerve, which is called secondary sciatica; a few are primary, namely sciatic neuritis.

Second: sciatica is mostly unilateral, not accompanied by lumbar and back pain; pain is generally persistent, but also paroxysmal, when the pressure of spinal canal increases, the symptoms worsen, or radiate along the sciatic nerve path. Sciatic nerve trunk tenderness is obvious, gastrocnemius tenderness exists; pain and myasthenia are not parallel, general pain is heavier, but myasthenia is not obvious.

Third: in the acute stage, it is difficult to judge the motor function due to pain. Foot ptosis, gastrocnemius and Achilles tendon reflex can be detected, but Achilles tendon reflex can also be normal, knee reflex is normal, and superficial sensory disturbance is obvious. It should be differentiated from hip and thigh back pain diseases such as lumbar muscle strain and buttock fibrohistitis.

matters needing attention

For the condition of sciatic neuralgia, we need to pay more attention and recuperation, do not do some heavy physical work, must pay attention to the sitting position and sleeping position, do not oppress the sciatic nerve, otherwise it will make the development of the disease worse.
