Carpal Tunnel Steroid Injections
Ultrasound-Guided Corticosteroid Injections

Carpal tunnel syndrome is a common condition caused by pressure on the median nerve as it passes through the carpal tunnel, a narrow passage of bones and ligament on the palm side of the wrist. When the tissues in this tunnel swell, the nerve is compressed, disrupting the signals it carries to part of the hand.

It is more common in women, during pregnancy and the perimenopause, and in people with diabetes, an underactive thyroid or jobs and hobbies involving repetitive wrist movements. In many cases there is no single obvious cause.

Left untreated, the pressure on the nerve can become persistent, so treating it earlier to relieve symptoms and protect the nerve is often the better course.

Symptoms come from the median nerve being squeezed, so they follow the part of the hand that nerve supplies:

• Numbness and tingling in the thumb, index, middle and half of the ring finger, often described as “pins and needles”.
• Night-time pain that wakes you and is often relieved by shaking or hanging the hand, a classic feature.
• Weakness or clumsiness in the hand, with a tendency to drop things or struggle with fine tasks such as buttons or keys.
• A feeling of swelling in the fingers even when none is visible.

Symptoms typically start gradually and may come and go before becoming more constant. The little finger is usually spared, which helps distinguish carpal tunnel from other nerve. problems. An ultrasound assessment confirms the diagnosis and rules out other causes.

At the Harley Street Ultrasound Group, your appointment begins with a diagnostic ultrasound assessment, performed by your specialist consultant doctor. Ultrasound shows the median nerve and the surrounding tendons in real time and is used to confirm carpal tunnel syndrome. A swollen, compressed nerve has a recognisable appearance on the scan, and rules out other causes of hand symptoms, such as tendon problems, ganglion cysts or wrist arthritis.

Crucially, the same ultrasound that confirms the diagnosis then guides the injection. Your consultant can see the median nerve clearly on the screen and place the needle precisely beside it under real-time, so the injedtion is delivered where it is needed and the nerve itself is identified and carefully avoided.

If the assessment shows that a different treatment would serve you better, your consultant will tell you on the day. See “What if I don’t need an injection?” below.

An ultrasound-guided steroid injection is one of the most effective non-surgical treatments for carpal tunnel syndrome. It works by placing a small amount of corticosteroid precisely beside the median nerve within the carpal tunnel. The steroid reduces the inflammation and swelling that are compressing the nerve, which in turn relieves the numbness, tingling and night pain.

Because the procedure is performed under real-time ultrasound, your consultant can see the median nerve clearly and place the needle accurately alongside it, so the nerve is identified and avoided rather than risked, and the medicine reaches exactly the right spot. This precision is what makes an ultrasound-guided injection both safer and more reliable than a “blind” injection given by feel.

For many people the injection settles symptoms and can delay or avoid the need for surgery. Your consultant will discuss whether an injection, a wrist splint, or onward surgical referral is the right next step for you.

Most patients find the injection far more comfortable than expected. The needle used is fine, and because it is guided by ultrasound the consultant can place it efficiently without probing for the right spot. You typically feel a small sting and a brief sensation of pressure. This is normal and settles quickly.

The appointment usually takes around 20–30 minutes from assessment to completion:

• Your consultant scans the wrist to confirm the diagnosis and locate the median nerve.
• The skin is cleaned and prepared.
• The injection is delivered under live ultrasound guidance, beside the nerve.
• You rest briefly and are given aftercare guidance before you leave.

There is no general anaesthetic and no overnight stay. You can usually drive yourself home, though arranging a lift is sensible if your wrist feels sore afterwards.

Your injection is performed by a consultant specialist doctor, not a physiotherapist, nurse or GP. This matters, as the majority of MSK injections in the UK are delivered by non-consultant practitioners, often without ultrasound image guidance.

At the Harley Street Ultrasound Group, you receive both the clinical judgement of a senior specialist and the precision of real-time ultrasound examination in a single appointment. Your consultant assesses the wrist, confirms the source of pain, performs the procedure and explains your aftercare personally.

We will never give you an injection you do not need. If, after your ultrasound assessment, your consultant decides an injection is not the right treatment for you, the procedure simply won’t go ahead. You will be charged at our standard diagnostic ultrasound rate, not the full treatment price.

This is a deliberate commitment to clinical integrity. Some providers treat every appointment as a guaranteed procedure; we don’t. You can book knowing that you will receive a genuine specialist assessment first, and that treatment only proceeds when a senior clinician believes it is genuinely warranted.

If an injection isn’t appropriate, your consultant will explain why and set out the alternatives. This may include physiotherapy, a different injection, such as PRP, or onward referral, meaning you still leave with a clear plan.

Many patients notice an improvement within a few days to two weeks as the steroid reduces the swelling around the nerve, with night-time symptoms often among the first to ease. The full benefit usually builds over the following weeks.

A steroid injection has a good success rate for relieving the symptoms of carpal tunnel syndrome, particularly in milder and moderate cases. For some people a single injection brings lasting relief, for others the benefit lasts several months and the injection serves to delay or avoid the need for surgery, while symptoms are controlled. Results vary with how long symptoms have been present and how compressed the nerve is. Your consultant will give you a realistic picture based on your own assessment and ultrasound findings.

There is no significant downtime. You can return to everyday activities the same day, though it is sensible to avoid heavy gripping or repetitive, forceful wrist use for 24–48 hours. Some mild soreness at the injection site for a day or two is normal.

Your consultant may recommend wearing a wrist splint, especially at night, to rest the wrist in a neutral position and help the symptoms settle. Simple changes to activities that aggravate the wrist, and short breaks from repetitive tasks, can also help the benefits last longer.

You will receive clear written aftercare guidance, and our team remains available if you have any questions as you recover.

For mild to moderate carpal tunnel syndrome, an ultrasound-guided steroid injection is often the right first step. It is non-surgical, requires no general anaesthetic and no downtime, and for many people relieves symptoms and can delay or avoid the need for surgery altogether.

Surgery (carpal tunnel release) is generally considered when symptoms are severe or long-standing, when there is muscle wasting or constant numbness suggesting significant nerve compression, or when injections and splinting have not given lasting relief. In those situations an injection may still be useful as a temporary measure while surgery is arranged.

The best way to know which path suits you is a proper assessment. Your consultant uses the ultrasound findings and your symptoms to advise honestly, and if surgery is the better option, will arrange onward referral rather than proceed with an injection that may not be necessary.

An ultrasound-guided steroid injection for carpal tunnel syndrome at The Harley Street Ultrasound Group is £525, all fees inclusive. There are no extra charges for the consultant assessment, the diagnostic ultrasound, the procedure itself, or your written report.

What’s included in the price:

• Consultant specialist assessment and diagnostic ultrasound
• Ultrasound-guided steroid injection procedure
• All consumables and the corticosteroid medication
• Written report and tailored aftercare guidance
• No referral required and no waiting list

Importantly, if your consultant assesses you and decides an injection is not clinically appropriate, you are charged only at our standard diagnostic ultrasound rate, not the procedure price. We accept self-pay and most major UK private health insurers; please confirm cover with your insurer before booking.

Coming to us privately does not affect your NHS care. Our goal is to get you answers and treatment quickly, without the long waits often involved in accessing injection therapy or hand-clinic appointments on the NHS.

You are seen by a consultant specialist who can assess, diagnose and, where appropriate, treat your carpal tunnel syndrome in a single visit. Your report and images can be shared securely with your NHS GP or any specialist, and if your situation needs onward NHS care, for example a surgical opinion, your consultant will write to your GP accordingly.

We don’t want you waiting months with numbness and disturbed sleep when effective treatment is available now.
