What is the Sciatic Nerve
"Sciatica" is not a specific disease name, but a "general term for symptoms such as pain and numbness" that occur when the thick "sciatic nerve," which runs from the lower back to the legs, is compressed or irritated for some reason.
[Main Causes]
○ Lumbar Disc Herniation
The intervertebral disc, which acts as a cushion for the spine, protrudes and compresses the nerve. It is characterized by being common in relatively younger age groups (20s to 40s).
○ Lumbar Spinal Stenosis
Due to aging or other factors, the spinal canal, which is the pathway for nerves, narrows and compresses the nerves. It is commonly seen in middle-aged and older people aged 50 and over.
○ Piriformis Syndrome
This occurs when the "piriformis" muscle, located deep in the buttocks, becomes stiff and compresses the sciatic nerve that runs underneath it. It can be triggered by long periods of sitting or muscle fatigue from sports.
[Characteristic Symptoms] "Sharp, electric-like pain" or "numbness" running from the buttocks to the thighs, calves, and toes. Pain intensifies when sitting for long periods. Symptoms often appear in only one leg.
[Massage is Effective]
If the cause of sciatica is "muscle hypertonicity (stiffness)," massage is effective.
Piriformis Syndrome (stiffness of the buttock muscles):
When the "piriformis" muscle located deep in the buttocks is stiff and compressing the nerve, properly loosening it can improve blood flow, relieve pressure on the nerve, and reduce pain.
Referred Pain (Trigger Points):
If "trigger points" (pain-triggering points) formed in the muscles of the lower back or buttocks are radiating pain toward the legs, releasing those points can alleviate symptoms.
Poor Circulation/Accumulation of Fatigue:
If blood flow around the nerves is poor due to muscle tension, the blood circulation-promoting effect of massage can accelerate recovery.
