Interventions targeting the perforating cutaneous nerve are relatively new to the literature, with a safe side-effect profile but lacking high-quality studies. Their effectiveness remains at the level of case presentations. According to the hypothesis expressed in these publications, coccydynia might be an overlooked cause due to the compression of the perforating cutaneous nerve where it pierces the sacrotuberous ligament and becomes superficial. Ultimately, it is hypothesized that injection of dextrose into this ligament and the sensory area of this nerve will resolve these symptoms due to nerve entrapment, similar to other entrapment neuropathies treated with 5% dextrose, like carpal tunnel syndrome.
