Ultrasound-Guided Injection Clinic in London

Targeted injections for joint, tendon and bursa pain, placed under real-time ultrasound guidance so the medicine reaches the intended structure. Carried out at our Marylebone clinic. From £250.

Injections are arranged rather than booked online, so we can confirm suitability, who will carry out the procedure and the cost with you first.

Two types of guided injection

Which is appropriate depends on your diagnosis. A diagnostic scan comes first, so the decision is based on what the ultrasound actually shows.

Anti-inflammatory

Cortisone injection

A corticosteroid placed into an inflamed joint, tendon sheath or bursa to reduce inflammation and pain. Most useful when it creates a window to progress with rehabilitation. Relief typically lasts weeks to months.

Viscosupplementation

Hyaluronic acid injection

Hyaluronic acid occurs naturally in joint fluid as a lubricant and shock absorber. In osteoarthritis its quality and concentration fall. Injecting it can reduce pain and improve function, usually given as a short course.

What ultrasound guidance changes

An unguided injection is placed using anatomical landmarks felt through the skin. With ultrasound, the clinician watches the needle on screen as it advances, so the medicine is delivered into the intended space rather than near it.

The evidence supports guidance improving the accuracy of needle placement compared with landmark technique. How much relief you get, and for how long, still varies between people — and is discussed with you beforehand rather than promised.

Why it is used

  • Accuracy. The needle is tracked in real time to the target structure.
  • Safety. Nerves, vessels and tendons are visible and can be avoided.
  • Comfort. Fewer passes are usually needed to reach the target.
  • No radiation. Ultrasound uses sound waves, unlike fluoroscopy or CT guidance.

Conditions commonly treated

Joints

Arthritis

Osteoarthritis of the knee, hip, shoulder and the small joints of the hands and feet, and inflammatory arthritis such as rheumatoid arthritis.

Tendons & bursae

Tendinopathy and bursitis

Rotator cuff and Achilles tendinopathy, tennis and golfer's elbow, subacromial and trochanteric bursitis.

Soft tissue & nerve

Entrapment and cysts

Carpal tunnel syndrome and other nerve entrapment, ganglion cysts, and ligament sprains and strains.

Start with a diagnostic MSK ultrasound to confirm what is causing the pain before deciding on treatment.

Who performs the injection, and how it is arranged

Who carries it out

Ultrasound-guided injections are carried out by Robert Mast, Consultant Radiologist, or by an MSK radiologist when available.

How it is arranged

Sonoworld provides the diagnostic ultrasound and the assessment. The injection itself is delivered by a partner service, at our Weymouth Street premises. Contact us and we will explain the process, who will carry out the procedure and the cost — from £250 — before anything is arranged.

From our practice

A typical presentation at the injection clinic

Shoulder pain that worsens on lifting the arm is one of the more common reasons people are referred to us for a guided injection. Diagnostic ultrasound will often show inflammation in the subacromial bursa alongside changes in the rotator cuff tendons — findings that are difficult to separate on clinical examination alone.

Where an injection is appropriate, ultrasound guidance lets the clinician see the inflamed bursa directly and place the medicine into it, rather than relying on surface landmarks. Response varies: some people notice a change within days, others gain less benefit, and an injection is usually most useful alongside physiotherapy rather than on its own. Your clinician will discuss what is realistic for your situation before anything is agreed.

General practice patterns from our clinic, not an individual patient case.

NHS or private?

Both routes are legitimate. The practical differences are usually about timing and continuity rather than the procedure itself.

NHS

  • Free at the point of use.
  • Usually requires a GP or specialist referral.
  • Waiting times vary by area and by service.

Private, at Sonoworld

  • Self-referral — no GP letter needed for the diagnostic scan.
  • Diagnostic scan and assessment usually available quickly.
  • Injection from £250, confirmed before anything is arranged.
  • Report and images provided to share with your GP or specialist.

Pricing

Ultrasound-guided injections start from £250. The exact cost depends on the site and what is involved, and is confirmed with you before anything is arranged — there is no obligation.

A diagnostic scan usually comes first

  • MSK ultrasound from £235 — instant verbal results, written report within 24 hours.
  • The scan confirms whether an injection is appropriate at all.
  • See all fees on our price list.

Frequently asked questions

Is an ultrasound-guided injection painful?+
Most people feel only mild discomfort. Local anaesthetic numbs the skin first, and because the needle is guided on screen, sensitive structures can be avoided and fewer passes are usually needed to reach the target.
How long does the appointment take?+
The injection itself is usually quick — often five to ten minutes. Including consultation, preparation and aftercare advice, allow around 30 to 45 minutes for the appointment.
What should I do afterwards?+
Rest the injected area for 24 to 48 hours and avoid strenuous activity. You will be given specific instructions for your injection type and condition before you leave.
How quickly will I feel relief?+
It differs by treatment. With cortisone, pain reduction often begins within a few days. With hyaluronic acid, improvement tends to be more gradual over several weeks. Response varies between individuals.
Are there side effects?+
Side effects are usually mild and temporary, such as localised pain or bruising at the injection site. Serious complications are uncommon. Your clinician will discuss the risks, benefits and alternatives with you as part of the consent process.
Can I book an injection online?+
No — injections are arranged rather than booked online. Sonoworld provides the diagnostic ultrasound and assessment, and the injection is delivered by a partner service at our Weymouth Street premises. Contact us and we will explain the process, who will carry out the procedure and the cost before anything is arranged.
