Sciatica: Why Pain Shoots Down Your Leg — and What Helps

Sciatica is not a diagnosis — it is a description: pain radiating along the sciatic nerve, from the lower back or buttock down the back of the leg, sometimes to the foot. Behind it there is almost always an irritated nerve root in the lumbar spine, most often from a herniated disc or a narrowed canal. The encouraging part: most episodes improve without surgery.

How it typically feels

• Electric, burning, or shooting pain down one leg — usually worse than the back pain itself
• Worse with sitting, coughing, or sneezing
• Tingling or numbness along the same path
• Sometimes weakness lifting the foot or pushing off the toes

What helps in the first weeks

Staying gently active beats bed rest — short walks, position changes, and anti-inflammatories as your doctor allows. Most flare-ups calm down substantially within 4 to 6 weeks. Physical therapy accelerates recovery and teaches you how to protect the spine afterward.

When it needs a specialist

See a neurologist if pain persists beyond a few weeks, keeps returning, or comes with progressive weakness or numbness. An exam plus, when needed, imaging and an EMG can pinpoint which nerve root is involved and how irritated it is — which is what separates "keep doing therapy" from "consider an injection or surgical consult". Loss of bladder or bowel control with leg symptoms is an emergency: go to the ER.

The long game

Recurrent sciatica is usually a spine that needs a better plan, not a stronger painkiller. At our Miami practice we map the nerve involvement precisely and build treatment around it — therapy, targeted medications, and coordination with interventional colleagues when an injection or surgical opinion is genuinely warranted.
