the medical professional administering the injection draws up the corticosteroid into a syringe. a local anesthetic (such as lidocaine) may simultaneously be drawn into the syringe. next the area to be injected is selected. typically the skin over the area to be injected is sterilized with a liquid solution either alcohol or betadine. sometimes the area is topically anesthetized by rapid cooling using a spray such as ethyl chloride. the needle of the syringe then is inserted into the tissue to be injected and the solution is ejected from the syringe into the area of inflammation. the needle then is withdrawn and a sterile bandage is applied to the injection site.
