Trigger Point Injections A trigger point is an area of tissue that is tender when compressed and may give rise to a referred pain and tenderness. Trigger points are often found along the spine and in the neck and shoulder area. Trigger point injections are done in the office, and take approximately 5 minutes. You will be kept for observation between 10 and 30 minutes after the procedure. You should use icepacks to the injection site for the rest of the day. It is suggested that you eat prior to your visit and take any routine medications, unless otherwise instructed by your pain physician. You may ask a family member or friend to drive you home after the procedure, though this is not mandatory. For more information regarding this procedure, please speak to your pain physician at your next scheduled visit.
