Sciatica is nerve pain that shoots from your low back down one leg. Four signs tell you it is a pinched nerve, three red flags mean see a doctor now, and most cases heal in weeks without surgery.
Leg pain that starts in your back is its own animal. Ordinary muscle strain aches where you pulled it. Sciatica travels: it runs from the low back through the buttock and down the back of one leg, because the problem is not the leg at all.
The problem is a pinched nerve root in your spine. The leg is just where the alarm rings.
That difference changes what you should do next. Here are the four signs that say sciatica, the three that say see a doctor now, and what actually helps while it heals.
Four Signs Your Leg Pain Is Sciatica
The Mayo Clinic describes a pattern that is hard to mistake once you know it. Check your pain against these four.
- It travels a path. The pain follows a line from your low back to the buttock and down the back of the thigh and calf, not one fixed spot.
- It feels electric. A sharp, burning pain, sometimes like a jolt or electric shock, that can get worse when you cough, sneeze or sit for a long time.
- It picks one side. Sciatica usually affects only one leg at a time. Pain in both legs is rare.
- It brings pins and needles. Numbness, tingling or muscle weakness can show up in the leg or foot, sometimes in a different spot than the pain.
One more clue that helps: hip problems tend to hurt in the groin and flare when you put weight on the leg. Sciatica starts in the low back and radiates down. Numbness and tingling point to the nerve, not the hip.
Three Signs That Mean See a Doctor Now
Most sciatica is painful but not dangerous. Three symptoms are different. Mayo Clinic says to get immediate medical care for any of these.
Sudden numbness or muscle weakness in a leg. A leg that suddenly will not hold you, or a foot you cannot lift, can mean the nerve is being seriously compressed.
Pain after a violent injury. Sciatica that starts after a fall or a traffic accident needs to be checked, not waited out.
Trouble controlling your bowels or bladder. This is the rarest and most urgent flag. It can signal severe nerve compression that needs treatment right away.
Most people recover fully from sciatica caused by herniated disks, often without treatment.
Harvard Health adds a second tier worth an office visit rather than a wait: sciatica for the first time when you are over 55, severe symptoms, a fever along with the pain, or a history of cancer.

The Cleveland Clinic playbook starts simple: ice for the first few days to calm pain and swelling, then switch to heat, about 20 minutes at a time either way. Over-the-counter anti-inflammatory medicine can help with both pain and swelling.
The counterintuitive part is movement. A day or two of taking it easy is fine, but after that, gentle activity beats the couch. Stretching and light movement relieve pressure on the nerve and help it heal.
Physical therapists lean on a short menu of gentle moves: knee-to-chest, bridging, cat-cow, and a light lying back extension. If a movement makes the leg pain clearly worse, stop and tell your doctor.
The Bed Rest Instinct That Slows Healing
Sciatica invites bad instincts. Each of these feels sensible in the moment.
Rest until it stops hurting. Too much rest can make the pain worse and slow recovery. Short rest, then light movement, is the evidence-backed order.
Shooting leg pain means surgery is coming. It almost never does. Most people recover without surgery, which is reserved for severe cases with serious weakness or red-flag symptoms.
It is just part of getting older. The most common cause is a herniated disk, most likely between ages 20 and 50. Age-related bone spurs are one cause, not the whole story, and treatment works at any age.
