You get up from the couch just like any other afternoon. And then it happens: an electric jolt starts in your buttock and shoots down the back of your leg, as if someone had flipped a switch you didn\u2019t even know you had. You stop halfway, one hand on your back, holding your breath. This isn\u2019t just any muscle strain. It\u2019s that pain so many people describe with the same word, almost always in a hushed voice and with a look of fear on their faces: sciatica<\/strong>. <\/p>\n\n

If you’ve come this far looking for answers, the first thing to know is this: most cases of sciatica get better\u2014and they do so without surgery. But to make a full recovery, it’s important to understand what’s really going on, which symptoms you shouldn’t ignore, and what to do today. Let’s take it one step at a time. <\/p>\n\n

What is sciatica (and why isn’t it a diagnosis)?<\/h2>\n\n
\"Illustration<\/figure>\n\n

Here\u2019s the first surprise: sciatica isn\u2019t a disease<\/strong>. It\u2019s a symptom. It\u2019s the name we give to the pain that travels along the sciatic nerve\u2014the longest and thickest nerve in your entire body, which in some places is almost as wide as your little finger. That nerve originates from the junction of several nerve roots in the lumbar and sacral regions (levels L4, L5, S1, S2, and S3), runs through the buttock, and descends along the back of each leg to the foot. <\/p>\n\n

When something irritates or compresses that nerve or its roots, the characteristic pain sets in. That\u2019s why saying \u201cI have sciatica\u201d is like saying \u201cI have a fever\u201d: it describes what you\u2019re feeling, not the cause. And the cause is exactly what needs to be identified in order to treat you properly. That difference\u2014which may seem like a subtle distinction\u2014changes everything: you don\u2019t treat sciatica \u201cin general\u201d; you treat the specific problem that\u2019s causing it. <\/p>\n\n

Did you know…?<\/strong> The sciatic nerve is so long that it connects your lower back to the sole of your foot. That’s why a problem in your lower back can cause tingling in your toes, even if your foot is perfectly healthy. <\/p>\n\n<\/blockquote>\n\n

Why Does It Happen? The Most Common Causes <\/h2>\n\n

In the vast majority of cases, sciatica originates in the lumbar spine. The most common cause is a herniated disc<\/strong>: one of the discs that cushions your vertebrae slips out of place or ruptures, and its contents press on a nerve root. It is estimated that about 85% of sciatica cases are related to a disc problem, especially among people aged 30 to 50. <\/p>\n\n

But that’s not the only explanation. These are the most common ones: <\/p>\n\n

The good news is that, whatever the cause, the road to recovery is pretty much the same in the most common cases. The bad news\u2014let\u2019s be honest\u2014is that none of them get better on their own overnight. It takes some patience and, above all, staying active. <\/p>\n\n

Sciatica has a fairly distinctive “pattern.” It almost always affects only one side<\/strong> of the body, and the pain follows the path of the nerve: <\/p>\n\n
