Clarify the diagnosis
Sciatica refers to symptoms associated with the sciatic nerve, often pain, numbness or tingling down one leg. The underlying cause and urgency can differ. Tell your clinician about new weakness, numbness or other changes before relying on a general back-pain program. Acupuncture should be considered only in the context of the diagnosed condition and medical plan.
Calibrate expectations
NCCIH describes reviews suggesting possible benefit for sciatica, but it judges the quality insufficient for definite conclusions. Do not turn that uncertainty into a claim that acupuncture repairs a disc or releases a compressed nerve. Ask what symptom or activity would be tracked and what the practitioner would do if no meaningful progress occurs.
Consider the whole plan
Compare a possible trial with recommended exercise, physical therapy, medicine or specialist evaluation as appropriate. Ask about treatment frequency, fees, needle safety and a follow-up date. Continuing visits despite worsening neurologic symptoms or lost function would be a poor substitute for medical review.
Questions and answers
Can acupuncture identify the cause of leg pain?
No. A qualified medical evaluation is needed to determine the cause and whether urgent assessment is appropriate. Tell the clinician promptly about new weakness or other neurologic changes, rather than assuming every leg symptom is routine sciatica.
