  2. 2.Sciatica

    The sciatic nerve is the largest nerve of the human body, and it runs through the buttock, down the thigh and into the calf, sending information to the muscles in the back of the thigh and leg, as well as the surrounding skin. The sciatic nerve itself is supplied by nerves coming from the spine in the lower back. Sometimes, one of the disks separating the vertebrae (bones of the spine) may bulge out a little bit, putting pressure on one of these nerve roots, causing sciatica, or shooting pain down the sciatic nerve.

    Problem will resolve itself within several weeks in 80-90% of cases.
