Sciatica (lumboischialgia) is about the longest nerve in the human body, which is as thick as the thumb.

It consists of five small nerves and runs from the bottom of the spine, down the back of the buttock, and down the back of the legs to the soles of the feet.

Whatever pressure is created in it, causes

irritation

and can cause

pain, 

Telegrafi reports.

The pain starts in the lower back and spreads, but it can also appear in the lower knee or in the calf, where it is more visible.

People also have difficulty bending their legs at the knees, but the pain can even appear in the other leg.

Sciatica can cause mild pain, which can be controlled by taking analgesics, but the pain can become much worse and force the patient to stay at home for days.

Sciatic nerve pain is often felt when sneezing, coughing, going to the toilet, or when you are sitting and can be accompanied by back pain.

Most sciatica pain improves within a few weeks and does not result in permanent damage.

Sciatica is not the first medical diagnosis, but it is one of the most common back problems today.

Most people try to relieve the pain with the help of drugs that have a short-term effect.
