You wake up and there it is again—sciatica pain. Around 40 percent of people will experience sciatica pain in the legs and back, from irritation of the sciatic nerve, in their lifetime. But that doesn’t mean it’s “normal” or that you have to continue suffering. Chronic sciatica may come and go, or it may be in the background most of the time, flaring up now and then. If you woke up with the pain this morning, it’s likely that you didn’t get good, restful sleep last night.
