Sciatica
Although conditions of the back of course mostly affect this body part, they can also cause pain in the legs as well. For example, sciatica, the inflammation of the sciatic nerve (a nerve that begins in your lower back and travels all the way down to your legs and feet) can lead to leg pain. Sciatica is not usually diagnosed properly right away. It can also be hard to treat, as symptoms sometimes seem to go away on their own. Like
other conditions of the spin, sciatica can develop gradually over time or it can come on suddenly. Acute sciatica can be the result of an injury or arthritis.
