Tired of Chronic Pain?


Ganglion Impar Block for Treatment of Coccydynia

Coccydynia is an uncommon pain located at the tip of the tailbone.  It usually occurs after trauma but many times the cause is unknown.  The symptoms of coccydynia include pain in the tailbone area, sitting, during sex or bowel movements.  The pain may be dull and aching or sharp when pressure is applied to the area such as when sitting.  The treatment of coccydynia begins with conservative modalities such as rest, non-steroidal anti-inflammatory medications and cushioning devices for sitting.  This month an article was published in Pain Medicine by Gunduz, Sencan and Kenis-Coskun.  This is the first study that includes a series of patients and therefore carries some statistical weight.  All patients in this study failed conservative modalities.  They underwent a nerve block called a Ganglion Impar Block.  Success of the injection was judged by a 50% reduction in their pain.  After 19 technically successful injections, 18 patients had pain relief.  The median pain relief was 6 months after the injection.  The injections were not curative.  However, since in some patients, this condition is difficult to treat a 6 month median period of pain relief would be welcome by many patients.  Although this is not by far a definitive cure, it may bring hope to many patients who suffer from this condition.
