Pudendal neuralgia (PN) is a chronic nerve compression syndrome causing neuropathic pain. Treatment includes medication, infiltration and decompressive surgery. Medicinal treatment involves the use of drugs that have proved effective in other areas, such as shingles or diabetes. There is no consensus on the molecules to be used for pudendal nerve infiltration (PNTI), and less than half of patients experience short-term relief. The only risk factor for failure is the duration of pain. Our study proposes to compare the usual treatment with a placebo, as no type of infiltration has been compared with a placebo.
