Overview
Suprascapular nerve block is a targeted treatment used to reduce shoulder pain when nerve irritation contributes to symptoms. Shoulder pain can arise from several conditions including shoulder arthritis, rotator cuff disorders, frozen shoulder, bursitis, or irritation of the nerves supplying the joint. These problems may lead to persistent pain, stiffness, weakness, and difficulty performing everyday activities.
The suprascapular nerve supplies a large portion of the shoulder joint and surrounding structures. When this nerve becomes sensitised it can contribute significantly to ongoing pain and restricted movement. A suprascapular nerve block aims to reduce nerve related pain, improve comfort, and allow better participation in rehabilitation and daily activity.
Who this treatment helps
A suprascapular nerve block may be suitable for people experiencing:
- Shoulder arthritis causing ongoing pain and stiffness
- Rotator cuff related shoulder pain
- Frozen shoulder with reduced range of motion
- Persistent shoulder pain affecting sleep
- Pain interfering with work or daily activities
- Limited improvement despite physiotherapy or medication
A consultant assessment is required to confirm whether suprascapular nerve block is appropriate for the source of symptoms.
What is a suprascapular nerve block
A suprascapular nerve block is a minimally invasive procedure where local anaesthetic, sometimes combined with steroid medication, is injected near the suprascapular nerve. The injection aims to calm nerve irritation, reduce pain signals, and improve shoulder comfort.
Ultrasound guidance is typically used to accurately identify the nerve and surrounding structures. This improves precision and safety while minimising discomfort during the procedure.
The treatment may be used diagnostically to confirm whether the nerve is contributing to pain and therapeutically to provide relief.
Procedure and recovery
The procedure is performed as a day case and usually takes only a short time.
- You are positioned comfortably for the injection
- The skin around the shoulder is cleaned and numbed
- Using ultrasound guidance the needle is placed near the suprascapular nerve
- The medication is injected to calm nerve irritation
- You are monitored briefly before returning home
After the procedure some people experience temporary numbness, heaviness, or mild soreness around the shoulder. These effects usually settle within hours to a few days.
Most patients return home the same day and resume light activities shortly afterwards. Your consultant may recommend continuing physiotherapy once pain improves to support longer term recovery.
Benefits
- May significantly reduce shoulder pain
- Can improve range of movement and comfort
- Supports physiotherapy and rehabilitation
- Minimally invasive with a short recovery period
- May reduce reliance on pain medication
Possible risks and side effects
Suprascapular nerve block is generally safe when performed by experienced clinicians, but some side effects may occur.
- Temporary soreness or bruising at the injection site
- Mild numbness or heaviness around the shoulder
- Light headedness
- Temporary increase in pain
- Infection or bleeding, which are rare
Your consultant will explain individual risks and ensure the treatment is appropriate for your condition.
Safety note
A full consultant led assessment is essential before treatment. Please inform your clinician about any medical conditions, medications, allergies, or previous reactions to injections. This helps ensure the procedure is planned safely.
Arrange a consultation to discuss whether suprascapular nerve block may be appropriate for your shoulder pain.
