The Cost of Cortisone Injections in London: A Complete Guide

Doctors perform over 500,000 cortisone injections every year in the UK for joint and tendon problems. But what should a cortisone injection cost in London — and is it worth the money? This guide covers the benefits, the risks, the realistic price range, and why the cheapest shot can prove the most expensive mistake.

Dr Masci’s one-stop ultrasound-guided cortisone injection costs £400 at his Chelsea clinic, including consultation and diagnostic ultrasound. For a full UK-wide breakdown, see our companion guide on private cortisone injection costs in the UK.

What is cortisone?

Cortisone injections contain corticosteroids — a group of steroid drugs that reduce inflammation. Cortisone differs completely from anabolic steroids, which build muscle. Reducing inflammation reduces pain and swelling in musculoskeletal conditions such as arthritis and tendonitis.

What does a cortisone injection treat?

Good evidence supports cortisone for hip, knee, and thumb arthritis, as well as for persistent pain after an ankle sprain. The effect is real but short — typically up to three months.

Cortisone also helps several tendon problems: plantar fasciitis, shoulder tendons and bursitis, De Quervain’s tenosynovitis, and trigger finger. We avoid cortisone for tennis elbow and golfer’s elbow, where it harms long-term outcomes. Dr Masci has published on the evidence for cortisone injections in tendonitis. Cortisone also works well for carpal tunnel syndrome and IT band syndrome.

How do we administer cortisone injections?

We use antiseptic skin preparation and sterile equipment. Crucially, we target the joint or tendon with ultrasound. Ultrasound improves accuracy, and seeing the needle means avoiding nerves and blood vessels. We regard ultrasound as essential — yet not every practitioner has the skills. Ask these four questions before any ultrasound-guided injection.

What are the risks of cortisone injections?

Used correctly, cortisone injections are safe. The most common side effect is a ‘steroid flare’ — increased pain starting around 6 hours after the injection and lasting up to four days. Rest, cold packs, and paracetamol or ibuprofen settle it. Contact your doctor if pain persists beyond four days.

Cortisone temporarily weakens tendons and cartilage, so rest for up to 7 days after the injection — longer for football, basketball, or sprinting. Less common side effects include skin thinning and colour loss (reduced by lower doses and ultrasound guidance), infection (around 1 in 10,000), a transient rise in blood sugar in diabetics, and facial flushing for 1–2 days.

When does a cortisone injection start to work?

Cortisone generally starts working after seven days, sometimes taking up to two weeks, with peak effect at 4–6 weeks. Pain relief typically lasts three months, occasionally six.

How many cortisone injections can I have?

No exact rule exists. We accept up to three injections into a single area, spaced at least six weeks apart. Injections into different areas are safe. For longer-term problems, the alternatives below avoid repeated cortisone altogether.

How much do cortisone shots cost in London?

If you have private insurance, your plan covers the cost of the cortisone injection — we accept all major insurers.

For self-paying patients, the cost of a cortisone injection in London varies enormously. Some clinics charge over £700; patients regularly tell us they have been quoted £600–£2,000 once separate consultation, imaging, and injection appointments stack up. Others advertise £250.

Why do some London clinics offer cortisone injections for £250?

Usually for one of two reasons. Some skip ultrasound — and blind injections are measurably less accurate and less effective. Others use non-medical practitioners: nurse practitioners, physiotherapists, podiatrists, even beauty therapists, who face far less regulation than doctors and often lack proper injection training.

Dr Masci is a Sports and Exercise Medicine consultant and an expert in ultrasound-guided injections. He has published research on injections, speaks at international conferences, and teaches injection techniques to doctors across the UK and Europe. You want the best surgeon for your operation — apply the same standard to your injection. Do your homework, and ask these four questions first.

Are there alternatives to cortisone?

Yes, and for longer-term problems, they often deliver better value. Hyaluronic acid — such as Durolane — lubricates the joint, reduces pain, and lasts over a year from a single £490 injection. Platelet-rich plasma uses concentrated platelets from your own blood to treat joints and tendons. For stubborn knee arthritis, Arthrosamid lasts at least five years. Dr Masci will recommend the right option for your condition at your consultation — and he will tell you when cortisone is not the answer.

Frequently asked questions about cortisone injection costs in London

What is a fair cost for a cortisone injection in London?

Around £350–£500 all-inclusive for an ultrasound-guided injection performed by an experienced doctor, covering consultation, diagnostic ultrasound, and the injection in one visit. Prices well below this usually cut corners; prices well above this usually reflect multiple separate appointments rather than better care.

What is the cost of a cortisone injection in the UK outside London?

UK-wide, expect £250–£1,000 depending on the clinic and pathway. Our guide to private cortisone injection costs in the UK covers the full picture, including what your fee should always include.

Does insurance cover a cortisone injection?

Yes. All major UK private insurers cover consultations and cortisone injections with Dr Masci. Our admin team can assist with pre-authorisation.

Is a cortisone injection worth the cost?

For an acutely painful, inflamed joint or tendon — yes, it remains the fastest-acting option. For long-standing arthritis, longer-lasting injections such as Durolane or Arthrosamid usually offer better value per month of relief. The consultation determines which suit best addresses your problem.

Final word from Sport Doctor London about cortisone injection cost in London
