What is sciatica?
Sciatica is the irritation of the sciatic nerve, which travels from the low back all the way down to your toes.
The sciatic nerve is the largest nerve in the body and therefore has a number of potential places it can be irritated. Because the nerve is so far reaching, it has many points it can affect as well.
The pain you experience can be in the spine, past the hip, down into the buttocks, through the thigh and even down to the toes. People who suffer from sciatica sometimes find it difficult to sit, sleep and sometimes walk due to the pain these daily activities cause.
