Sciatic injury can be largely avoided by advancing the needle slowly and asking the patient to report any tingling, numbness, electrical sensations, or pain down the back of the leg. At the first signs of discomfort, the needle should be pulled back and then redirected laterally. Injecting in the outer third of the muscle also lowers the chance of sciatic nerve injury.
