Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 and older with diagnosed pudendal neuralgia who have not responded to standard drug treatments.

Probably not a fit

Patients with ongoing infections, certain neurological or psychiatric conditions, or those on anticoagulants may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study aims to assess the effectiveness of therapeutic infiltrations of the pudendal nerve using lidocaine, compared to a saline placebo, in alleviating pain associated with pudendal neuralgia. Participants will be adults who have experienced treatment failure with standard medications for neuropathic pain. The study will measure pain relief one month after the infiltration, focusing on the potential benefits of this intervention in a population that has limited options for effective pain management. The research seeks to establish a clearer understanding of the efficacy of nerve infiltration treatments.

Why it matters

Potential benefit: If successful, this study could provide a new, effective treatment option for patients suffering from pudendal neuralgia.

How similar studies have gone: While there is limited consensus on the best treatment for pudendal neuralgia, previous studies have shown mixed results with similar infiltration approaches, indicating a need for further investigation.
