Hand Unit, Plastic Surgery Department Patient information sheet Steroid Injection This information leaflet is for patients who have had a steroid injection, or who may be considering having one. It explains what they are and what to expect. These are general guidelines and variations may exist depending on individual circumstances. Why has my surgeon recommended a steroid injection for me? Steroid can be injected into an area to reduce inflammation, swelling or pain. It only acts in the area that it is injected into. They can be given as a treatment for a number of conditions, including trigger finger, de Quervains and ganglion. Are other treatments available? Depending on the cause of the inflammation, pain or swelling, there maybe other treatments available, such as hand therapy. If these are an option for your condition then your surgeon will discuss these with you. Which steroid will be used? There are several steroid preparations available of varying strength– your surgeon will recommend one which is most appropriate for your needs. Depending on your condition, your surgeon will decide whether to inject a local anaesthetic at the same time. This does not reduce inflammation but will allow almost immediate temporary pain relief. How long will it take for the injection to work and how long will it last for? The short-acting soluble steroids give relief within hours and should last for at least a week. The longer-acting, less soluble, steroids may take a few days to become effective but may give benefit for 2 months or longer. If an anaesthetic has also been given, pain relief should occur within minutes but it will usually wear off in one to four hours. Do I need to do anything after the injection? The person giving you the injection will give you advice on resuming your normal activities and what you can do to help prevent recurrence of this problem. If you are given some exercise to do, it is important that you follow these instructions to get the most benefit from your treatment. What are the possible risks or side-effects? Side-effects are unlikely but occasionally people notice an increase in their joint pain within the first 24 hours after an injection. This usually settles on its own within a couple of days. Very rarely infection might be introduced into the joint at the time of an injection. Therefore if the joint becomes more painful and hot you should see
