Summary
This study tests whether injecting lidocaine into the abdominal wall can reduce chronic pain caused by trapped nerves.

- What this could lead to
- If it works, this could offer a simple, non-surgical option for people with chronic abdominal wall pain.
- What could go wrong
- This is a small, early-phase study with only 45 people and no placebo group, so results may not be conclusive. Lidocaine injections can cause pain, bruising, or rare allergic reactions.
