This information is organized into sections related to the area of the body where you are experiencing pain: general body pain along with foot, ankle and knee; and pain in the head, neck and spine. While not fully inclusive, this information will provide an overview of the conditions or causes of your pain that you and your PCA physician may discuss together. Once your procedure is scheduled with PCA, our team will provide you with complete information on the procedure as well as what to do in advance and how to care for yourself afterwards.
