Side effects and complications of cervical epidural steroid injections.

Two hundred and four cervical epidural injections of corticosteroids were performed on 142 patients for the treatment of cervical pain over a 1-yr period. Injections were performed at the C7-T1 interspace with 10-15 mL of 0.5% lidocaine containing 1 mg per kg of methylprednisone acetate. Four complications occurred: two dural punctures without sequelae; one episode of upper extremity weakness, which resolved in 24 hr; and one episode of nausea and vomiting lasting 12 hr. In addition, two side effects were frequently reported: stiff neck lasting 12-24 hr occurred in 13.2% of patients, and a mild facial flushing with subjective (but not objective) fever lasting about 12 hr occurred in 9.3% of patients. In this large series, the procedure appears safe to use in an outpatient setting.
