What might cause leg pain extending from the buttocks to the calf?

Leg pain radiating from the buttocks down to the calf is most commonly caused by sciatica, a condition involving irritation or compression of the sciatic nerve. Less common causes include tumors, blood clots (deep vein thrombosis), or spinal disorders such as a herniated disc or spinal stenosis.

Key points about buttock-to-calf leg pain:

• Sciatica is the leading cause, often triggered by a herniated disc, bone spur, or narrowing of the spine pressing on the sciatic nerve.
• Symptoms may include sharp, burning, or shooting pain, numbness, tingling, or muscle weakness along the leg.
• Serious causes like blood clots or tumors are rare but require prompt medical attention, especially if pain is sudden, severe, or paired with swelling or redness.

Because leg pain can stem from many overlapping conditions—some minor, some serious—identifying the root cause quickly matters. A free, instant, online symptom check can help you understand what may be causing your pain, evaluate urgency, and guide your next steps toward the right care. It takes just a few minutes and could save you time, worry, and unnecessary appointments.
