A method for providing a substantially painless injection of medication into a patient, including inserting an injection needle having an outside diameter greater than 0.20 mm and less than about 0.38 mm, and injecting a medicament through the needle and into the patient at a substantially constant volumetric flow rate of about 0.05 μL/s to about 50 μL/s that provides a painless injection. The method does not require the use of an anesthetic or that the medical personnel to spend a substantial amount of time performing the injection procedure, is relatively simple and inexpensive to perform and operate, and provides a relatively high degree of safety for both the medical personnel and for the patient.
