One of the most common questions we receive at Alton Pain Clinic is how often a cortisone injection can be repeated. There is no universal single answer, as it depends on the joint being treated, the underlying condition, and your individual response — but there are clear clinical guidelines that govern safe practice.
General Guidance on Frequency
As a general rule, most clinicians recommend no more than three to four cortisone injections per year into any single joint or soft tissue area.
At Alton Pain Clinic, our approach is always to use the lowest effective dose and to space injections appropriately. We typically advise leaving at least six to twelve weeks between injections to the same site.
Does the Limit Vary by Joint?
Yes. Different joints and tissue types carry different risk profiles with repeated injection:
- Large joints (knee, hip, shoulder): typically up to three to four injections per year
- Small joints (fingers, toes): clinicians tend to be more conservative due to the smaller tissue volume
- Tendons: repeated steroid injections near tendons (such as the Achilles) require particular caution due to the risk of tendon weakening
Our clinicians will always assess your individual circumstances before recommending further injections.
What If a Cortisone Injection Stops Working?
If you find that cortisone injections are becoming less effective over time, or that the relief is shorter-lived with each treatment, it is important to discuss this with your clinician. This may indicate disease progression or that an alternative treatment — such as Arthrosamid for knee osteoarthritis.
At Alton Pain Clinic, we take a long-term view of your musculoskeletal health, not a repeat-injection approach. Our clinicians will always discuss all available options with you.
Are There Patients Who Should Not Have Repeated Cortisone Injections?
Yes. Patients who may need more careful monitoring or who may not be suitable for repeated injections include those with:
- Diabetes — corticosteroids can temporarily raise blood glucose levels
- Osteoporosis — repeated steroid exposure can affect bone density
- A history of joint infection
- Compromised immune function
Your medical history will always be reviewed at Alton Pain Clinic before any injection is administered.

Frequently Asked Questions
Can I have a cortisone injection if I have diabetes?
Cortisone injections can temporarily raise blood sugar levels, so extra monitoring may be required if you have diabetes. Our team will discuss this with you beforehand and may liaise with your GP or diabetes specialist. It does not automatically mean you cannot have the injection.
What happens if I have too many cortisone injections?
Excessive cortisone injections into a joint over time can potentially weaken cartilage, increase the risk of infection, or cause soft tissue atrophy. This is why following clinical guidelines on frequency is important — and why Alton Pain Clinic monitors each patient’s treatment history carefully.
Is there a lifetime limit on cortisone injections?
There is no universally agreed lifetime limit, but cumulative exposure is always considered. If a joint requires very frequent injections to manage symptoms, this is usually a sign that a more definitive intervention — such as surgical review or a longer-lasting treatment — should be explored.
