A steroid delivery system including a mixing syringe having a first chamber and a second chamber and at least one hypodermic needle is provided. The first chamber of the mixing syringe contains a pre-measured volume of a local anesthetic and the second chamber contains a pre-measured volume of a corticosteroid. An improved mixing syringe and a method for treating pain using the steroid delivery system of the present invention is also provided herein. The improved syringe achieves mixing without the introduction or elimination of air and without puncturing or rupturing of a membrane, diaphragm or other material. The kit concept improves the speed of the procedure, sterility, accuracy of dosing, and immediate availability of disparate items to implement the procedure in a variety of medical practice settings.
