The study will use a local anesthetic called lidocaine, which is commonly used to numb tissues in a specific area, and a solution of sodium chloride, often referred to as saline. The purpose of the study is to evaluate the effectiveness of a procedure called a posterior perineal block, which involves injecting the anesthetic into the perineal area to manage pain.

Participants in the study will receive either the lidocaine solution or the saline solution through an injection. The study is designed to be double-blind, meaning neither the participants nor the researchers will know which solution is being administered to ensure unbiased results. The main goal is to assess the reduction in pain one month after the injection. The study will also look at the maintenance of pain relief over a period of three months and other factors such as anxiety and depression levels, using various questionnaires and scales.

The trial aims to provide insights into the management of chronic idiopathic ano-perineal pain and determine if the local anesthetic infiltration is an effective treatment option. Participants will be monitored for changes in their pain levels and overall well-being throughout the study period.
