Sciatica

Sciatica is a boo-boo in your bottom and leg that makes them feel silly. Your body has a really long and important road called the "sciatic nerve" that goes from your back all the way down to your toes. When something isn't happy with this nerve, it can cause a sore feeling in your butt and leg, like when you sit on a hard chair for a long time. Sometimes the boo-boo can be because a part of your back is hurt or squished, or maybe your muscles are really tight and need a good stretch. Doctors can help find out why your bottom is crying and give you special exercises or medicine to help make it feel better.
