✅ The UK's National Health Service (NHS) has included sciatica in its list of the 20 most painful human diseases.
✅ The condition is common in people over 50 due to age-related changes in the lumbar spine (osteochondrosis, herniation, and protrusion). However, sciatica is also common in younger people, and athletes and pregnant women are at risk.
✅ The sciatic nerve is the longest and thickest nerve in the body. It's a paired nerve—it runs symmetrically along both legs, has numerous branches, and innervates not only the muscles of the legs and feet, but also the joints (hip, knee, ankle, and foot joints), as well as the skin of the legs and feet.
This is why sciatic nerve damage causes not only pain but also loss of sensation, muscle weakness, and impaired joint function.
✅ The term "sciatica" was introduced in 1764 by the Italian anatomist and physician Domenico Cotugno, who was the first to describe the sciatic nerve and investigate the causes of its inflammation.
✅ Sciatica is sometimes called sciatica, but this is not entirely accurate. Sciatica is a collective term for all pain symptoms along the sciatic nerve. It can be anything from sciatica to sciatica. Therefore, "sciatica" is not the same as "sciatica," and it is incorrect to use the terms interchangeably.
