You may be offered an injection by your doctor to help manage your pain. We are going to look at what they are, how they work and if they are effective.

Corticosteroid is a prescription only anti-inflammatory drug and is different to anabolic steroids used by body builders and athletes.
It is frequently used to treat joint pain, arthritis and soft tissue disorders such as tendon pain or bursitis.

It is administered by a doctor or specially trained physiotherapist or nurse. It is usually combined with a local anaesthetic to numb the area before the steroid is given via the same needle.

 

How do steroid injections work and how effective is it?

The drug is released slowly into the local area and reduces inflammation which in turn reduces the pain and swelling associated with it. The length of time it works for is variable from a few days to many months and often this depends upon what is causing the pain.

We generally find that if the pain and swelling are relieved this makes it much easier to move the affected area which gives a window of opportunity to allow you to exercise and rehabilitate to gain a longer lasting improvement.

 

What are the side effects of steroid injections?

  • Pain and swelling in the local area on average lasting up to 48 hours
