Sciatica is a pain in the leg due to irritation of the sciatic nerve. The pain generally goes from the back of the thigh to the back of the calf, and may also extend upward to the hip and down to the foot. In addition to pain, there may be numbness and difficulty moving or controlling the leg. Typically, the symptoms are only felt on one side.
Although sciatica is a relatively common form of low back pain and leg pain, the true meaning of the term is often misunderstood. Sciatica is a set of symptoms rather than a diagnosis for what is irritating the nerve root and causing the pain. This is an important point because treatment for sciatica or sciatica-type symptoms will often be different depending on the underlying cause of the symptoms.
The first cited use of the word occurs in 1450 Oxford English Dictionary, 2nd Ed. "a1450 Mankind (Brandl) 484 Remembre my brokyne hede..3e, goode ser, & þe sytyca in my erme.".
