Overview
The ilio inguinal nerve travels through the abdominal wall and into the groin. It may become irritated after surgery such as hernia repair, abdominal procedures, injury, pregnancy related strain, or repetitive movement. Symptoms may include groin pain, lower abdominal pain, hypersensitivity, or pain triggered by pressure or certain movements.
A nerve block aims to reduce inflammation and nerve sensitivity and can help confirm the nerve as a pain source when symptoms improve after the injection.
Who This Treatment Helps
An ilio inguinal nerve block may be suitable for people with:
• Groin pain or lower abdominal pain
• Pain following hernia repair or abdominal surgery
• Burning, tingling, or sharp nerve pain patterns
• Pain worsened by movement or pressure
• Suspected nerve irritation or neuralgia
• Limited response to medication or physiotherapy
A consultation is needed to confirm suitability.
What Is an Ilio Inguinal Nerve Block
A targeted injection delivered near the ilio inguinal nerve. The injection typically contains:
• Local anaesthetic to temporarily numb the nerve
• Steroid medication to reduce inflammation
Ultrasound guidance is commonly used to improve accuracy and safety.
What to Expect During the Procedure
You lie comfortably on your back. The skin is cleaned and numbed, then the nerve is identified using ultrasound. A fine needle is guided into place and medication is delivered around the nerve. You are monitored briefly before discharge.
After the Procedure
Temporary numbness in the groin or lower abdomen can occur. Mild soreness is common. Some people notice immediate improvement, while steroid benefit may build over several days.
Your consultant may advise:
• Avoid strenuous activity for 24 to 48 hours
• Wear loose clothing
• Continue physiotherapy if recommended
• Monitor symptoms and report concerns
Benefits
• May reduce groin and lower abdominal pain
• Helps confirm nerve involvement
• Minimally invasive with short recovery time
• Can improve comfort with walking and daily movement
• May reduce reliance on medication
• Supports rehabilitation and activity planning
Possible Risks and Side Effects
• Temporary increase in pain
• Local bruising or soreness
• Temporary numbness
• Infection rare
• Bleeding
• Allergic reaction uncommon
• Very rarely irritation of nearby nerves or structures
When to Consider Other Options
If symptoms suggest other nerves or deeper pelvic pain pathways, your consultant may discuss genito femoral nerve block, pudendal nerve block, caudal epidural, or multidisciplinary pelvic pain management.
Safety Note
Inform your consultant about medications and medical conditions including blood thinners, allergies, diabetes, pregnancy, and recent infections. Avoid driving if numbness persists.
Arrange a consultation to discuss whether an ilio inguinal nerve block may help.
