For patients who feel concerned or anxious about their injections hurting, it is worth knowing that we have surveyed our patients regarding this and on average they have relayed that on a scale of 1-10 the most pain felt was around a 2. Every patient is numbed before the actual injection with lidocaine, this is typically the only thing that is felt by the patient. This injection of lidocaine is performed with the same size needle used to give the common flu shot and is considerably smaller than the needle used for an IV if you were to be sedated for the injection.
