A method for treating an inflamed tissue includes locally applying a solution comprising a corticosteroid and an anesthetic agent to the inflamed tissue so that the solution directly contacts the inflamed tissue. The corticosteroid may be a 4 mg/ml dexamethasone solution and the anesthetic agent may be a 1% lidocaine solution. The dexamethasone solution and the lidocaine solution may be mixed in a 1 to 3 ratio. Locally applying the solution may include penetrating the skin with a hypodermic needle, directing the hypodermic needle parallel to and past the inflamed tissue, and while withdrawing the hypodermic needle, spraying the solution directly onto the surface of the inflamed tissue.
