A mixture of medications containing local anesthetics and a corticosteroid is then slowly injected, the patient often experiences immediate relief from the local anesthetic but this is temporary and generally wears off after twenty four hours. The steroid medication may take up to forty eight hours to take effect but then provides long lasting relief.pain relief3
