Overview
The thoracic nerves run between the ribs and supply sensation to the mid‑back and chest wall. When these nerves become irritated—due to disc problems, muscular tension, joint inflammation or postural strain—they may trigger sharp, burning or radiating pain around the ribs.
A thoracic nerve block involves placing local anaesthetic, sometimes combined with steroid medication, around the affected nerve. This aims to calm inflammation and interrupt pain signals. In selected cases, PRP may be used as an alternative or complementary option, aiming to support tissue healing and reduce sensitivity.
Both treatments can be diagnostic and therapeutic. A nerve block may help confirm whether a specific nerve is contributing to symptoms.
Who this treatment helps
A thoracic nerve block or PRP may be considered for people with:
- Mid‑back pain radiating around the ribs
- Burning, tingling or nerve‑related discomfort
- Pain aggravated by twisting, deep breathing or certain movements
- Thoracic nerve irritation following injury or strain
- Persistent symptoms despite physiotherapy or medication
- Pain suspected to originate from intercostal or thoracic nerve pathways
A consultation is required to confirm suitability and identify the most appropriate treatment option.
What is a Thoracic Nerve Block/PRP?
A thoracic nerve block is a minimally invasive procedure that delivers local anaesthetic—and sometimes steroid—around the irritated nerve. This aims to reduce inflammation and provide temporary or longer‑lasting relief.
PRP therapy involves using a small sample of your own blood, which is processed to concentrate platelets. These platelets contain growth factors that may support tissue healing and reduce nerve sensitivity in selected cases. Evidence varies, and suitability depends on individual circumstances.
Ultrasound or fluoroscopy (X‑ray guidance) may be used to optimise accuracy and safety.
What to expect during the procedure
Your consultant reviews the plan and answers any final questions.
You lie comfortably on the procedure table.
The skin over the target area is cleaned and numbed with local anaesthetic.
Using imaging guidance, a fine needle is positioned near the affected nerve.
For a nerve block, local anaesthetic with or without steroid is injected.
For PRP, a blood sample is taken, processed, and the PRP is injected around the nerve.
You are monitored briefly before going home the same day.
The procedure typically takes 15–30 minutes.
After the procedure
- Temporary numbness or warmth in the mid‑back or chest wall is common.
- Mild soreness at the injection site may occur for a day or two.
- Nerve block relief may be immediate due to the local anaesthetic, with steroid effects developing gradually if used.
- PRP may take several weeks to show benefit, as it relies on natural healing processes.
- Most people resume normal activities the next day, avoiding strenuous exercise for 24 hours.
- Your consultant may recommend physiotherapy to support long‑term improvement.
Benefits
- May reduce mid‑back and rib‑radiating pain
- Can help confirm whether a specific nerve is the source of symptoms
- May improve mobility and breathing comfort
- Minimally invasive with a short recovery time
- PRP may help support tissue healing in selected cases
- Can support rehabilitation and posture correction
Possible risks and side effects
Thoracic nerve blocks and PRP are generally safe. Possible effects include:
- Temporary soreness or bruising
- Mild swelling at the injection site
- Light‑headedness
- Temporary increase in pain
- Rarely, infection or bleeding
- Very rare nerve irritation
Your consultant will discuss individual risks during your assessment.
When to consider other options
If symptoms persist or if the response is limited, your consultant may discuss:
- Thoracic epidural injections
- Thoracic facet joint injections or ablation
- Trigger point injections for muscular tension
- Physiotherapy or posture‑based rehabilitation
- Medication review
- Combined approaches for complex thoracic pain
Safety note
Please inform your consultant if you take blood thinners, have allergies, diabetes, active infection, are pregnant, or have had previous reactions to steroid, PRP or local anaesthetic. You may need someone to drive you home depending on the medications used.
Arrange a consultation to discuss whether a thoracic nerve block or PRP may be appropriate for you.
