The aim of this study was to evaluate the efficacy of coccygeal nerve blockade. Impar sympathetic ganglion blockade is a common treatment method used in coccygeal pain. However, experience with the coccygeal nerve is scarce in the literature. The investigator planned to follow up coccidynia patients who underwent impar sympathetic ganglion blockade and coccygeal nerve blockade for 3 months after the procedure. The investigator's aim is to compare the efficacy of coccygeal nerve blockade with impar blockade.
