Arthritis of the big toe — hallux rigidus — is a common cause of pain and stiffness. Where simple treatments haven’t worked, a cortisone shot in the big toe joint can help. So when should you consider a steroid injection in the big toe joint, and what are the options? 

When is a cortisone shot in the big toe joint helpful?

A cortisone injection isn’t the first treatment for big toe arthritis — it’s for cases that haven’t settled with simpler measures. 

Big toe arthritis usually responds to a stiff or rocker-soled shoe, gel pads, orthotics, anti-inflammatory measures such as ice and ibuprofen, and calf stretching and strengthening. When these haven’t controlled the pain, a steroid injection into the big toe joint is a useful next step. For the full picture on managing the arthritis itself, see our guide to hallux rigidus.

Is a cortisone shot in the big toe joint helpful?

Yes — a steroid injection is a powerful way to reduce inflammation and pain in the joint. A hallux rigidus injection is effective at improving toe symptoms. 

We inject under ultrasound guidance to ensure accuracy — the big toe joint is small, so precise placement matters. It’s important to understand that a cortisone shot in the big toe joint usually lasts only a few months, though in some people the relief lasts considerably longer. We also limit the number of cortisone injections into any one joint, because repeated cortisone can, over time, affect the joint surface.

For more on how cortisone works and its pros and cons, see our dedicated guide.

Are there other injection options besides cortisone?

Yes. Where cortisone has already been used, or isn’t suitable, we sometimes use hyaluronic acid or platelet-rich plasma (PRP) in the degenerative joint.

For a hallux rigidus injection, we often recommend hyaluronic acid, as it’s less expensive and requires only a single shot. PRP usually needs 2–3 injections over a few months. Which is right depends on your joint and what you’ve had before — worth discussing at your assessment.

Surgery is reserved for cases that fail all other treatment.

What to expect after the injection

Most people tolerate a hallux rigidus injection well. Some soreness for a day or two is normal, and ice and simple painkillers help. As with any injection, there are a few things to watch for.

When to seek advice after an injection. A short-lived increase in pain (a cortisone “flare”) for a day or two is normal. But contact your doctor if you develop increasing pain after the first couple of days, spreading redness, heat, swelling, or a fever — these can point to infection, which is uncommon but needs prompt assessment.

Frequently asked questions about a cortisone shot in the big toe joint

How long does a cortisone shot in the big toe last?

Usually a few months, though some people get considerably longer relief, and occasionally a single injection settles things for good. Because the effect isn’t permanent, we use the injection alongside footwear changes and rehabilitation rather than on its own.

How many cortisone injections can I have in my big toe?

We use them sparingly — repeated cortisone into one small joint can affect the joint surface over time. If the first injection helps but the pain returns, we’d usually consider hyaluronic acid or PRP rather than repeated cortisone.

Cortisone or hyaluronic acid for the big toe — which is better?

Cortisone settles inflammation and pain quickly. Hyaluronic acid is often preferred for the arthritic toe as a single, long-term option, avoiding repeated steroid injections. The best choice depends on your joint and whether you’ve already had cortisone.

Does the injection hurt?

There’s some discomfort, but the big toe joint injection is quick, and ultrasound guidance lets us use a fine needle with precise placement. Brief soreness afterwards is normal.

Will I still need surgery?

Often not, at least for a while. Injections, footwear, and rehabilitation control the pain in many people. Surgery is reserved for advanced arthritis that hasn’t responded — and an injection can be a useful way to delay it.

Is a cortisone injection safe if I’ve had a lot of steroids before?

Tell your doctor about previous steroid injections and any reaction to them. Very frequent cortisone injections can occasionally affect the body’s own cortisol levels, so where someone has had many injections, we’d usually consider a non-steroidal option such as hyaluronic acid instead.

Final word from Sport Doctor London about a cortisone shot in the big toe

Big toe arthritis becomes more common with age. We suggest simple treatments first, including a visit to a podiatrist. In more difficult cases, an ultrasound-guided cortisone injection into the big toe joint reduces pain — and when cortisone isn’t suitable or hasn’t lasted, hyaluronic acid or PRP are good alternatives.

If you have painful big toe arthritis, Dr Masci can assess you in London, including in-clinic ultrasound. Contact the team here or call +44 (0) 203 488 0350.
