“Sciatica, the sharp, radiating pain that travels from the lower back down the leg, is one of the most common nerve-related conditions. Its lifetime incidence reaches up to 40%, it peaks in the 30s and 40s, and the large majority of cases resolve without surgery. Here is the 2026 data on how common sciatica is, what causes it, and how recovery works, from primary sources only.

• Sciatica has a reported lifetime incidence of 10% to 40%.
• The annual incidence is about 1% to 5%; disc-related sciatica affects ~2.2% yearly.
• It accounts for roughly 5% to 10% of all low back pain cases.
• Peak incidence is in the fourth decade (30s), most common ages 30–50.
• The most common cause is a herniated lumbar disc pressing on a nerve root.
• An estimated 80% to 90% improve without surgery.
• About 30% still have troublesome symptoms at one year, showing why early care matters.”
