The Rhogam shot is typically administered in either the arm or buttocks. The level of pain experienced may vary depending on the injection site, but it is generally described as a mild discomfort. To determine where you will receive the shot, consult with your healthcare provider who will consider factors such as your medical history, preferences, and specific circumstances. They will be able to provide guidance and make an informed decision regarding the injection site that is most appropriate for you. It's important to remember that any discomfort experienced during the administration of the Rhogam shot is temporary and outweighed by its benefits in preventing complications during pregnancy.
