Corticosteroid injections
Corticosteroid injections are used to reduce inflammation in conditions such as trigger finger, de Quervain’s tenosynovitis, basal thumb joint arthritis and carpal tunnel syndrome. In many cases they are an effective treatment that allows surgery to be avoided. Corticosteroids are a synthetic version of hormones produced naturally by the adrenal glands.
How are corticosteroid injections given?
We perform the injection as an office procedure for trigger finger.
For joint injections, carpal tunnel syndrome or de Quervain’s tenosynovitis you will be referred to have the procedure performed under ultrasound or x-ray guidance by a radiologist, as this is likely to give a better outcome. You do not need to fast for the procedure and you will be awake throughout.
Frequently Asked Questions

You do not need to fast for the procedure and you will be awake throughout.
Are corticosteroid injections painful?
As with all injections there is some discomfort, and the amount varies from person to person. For this reason local anaesthetic is routinely used, either mixed with the injection or given separately to numb the area beforehand. After the local anaesthetic wears off you may notice pain or discomfort until the corticosteroid starts to take effect.
What should I do after a corticosteroid injection?
Take it easy. Applying cold packs to the area and/or taking paracetamol or ibuprofen will help with any discomfort. Rest the area for 24 hours and avoid strenuous activity for one week. If you have numbness from the local anaesthetic, avoid activities that could put you at risk of injury until the numbness has fully worn off later in the day.
What are the possible complications of corticosteroid injections?
Possible complications include atrophy of the skin and fat under the skin at the injection site, changes in skin pigmentation at the injection site, temporary irritation of the surrounding tissue, weakening of tendons (including tendon rupture) and joint infection. The injection can sometimes cause a short-term increase in pain due to inflammation, known as a “post-injection flare”. Corticosteroid injections can temporarily raise blood sugar levels in people with diabetes. Injections should not be given where there is, or has recently been, a local infection.
How often can I have a corticosteroid injection?
There are limits on how many times, and how often, a corticosteroid injection can be given in the same area. Usually no more than three injections to a single area are given. Talk to your hand surgeon about the limits and contraindications that apply to your individual circumstances.
What pain medication will I need afterwards?
Usually simple pain relief – paracetamol and ibuprofen – is all that’s needed. You can take this before or after your injection, or not at all.
