STEROID INJECTIONS

Steroid (sometimes referred to as a ‘cortisone’) is an anti-inflammatory solution which can be injected into joints or soft tissues with the aim to reduce pain as a result of inflammation. Dr Marwan utilises ultrasound to ensure the needle is placed precisely into the intended site and minimises any complications as a result of inaccuracy. For most conditions, steroid injections tend to work best if done as part of a wider package of care such as self management, exercises and healthier living. Local anaesthetic is generally used prior to the steroid injection, to help ease any discomfort. 

What happens during the procedure?

The site for the injection will usually be examined under ultrasound, then the skin cleaned using a cold cleaning solution. Local anaesthetic may be injected to numb the area prior to the steroid injection. When the injection is finished, the needle is removed and a small plaster or dressing is applied. For the majority of injections the process is very well tolerated and has minimal pain. If using anaesthetic, the pain might be instantly better.

What happens after the procedure?

The local anaesthetic effect will start to wear off 3-4 hours time following the injection. A minority of people may experience an increase in discomfort for 48-72 hours. It is advisable to avoid any aggravating activities for a few days following the injection to let everything settle down.

How long does it take to work?

The injection can reduce the pain in a matter of days, but for some it can take up to 6 weeks to take full effect.

How long does it last for?

This varies significantly among patients. For some it only lasts a matter of weeks, and for others many months. Having no response to the injection may mean the problem isn’t ameniable to steroid injections, or that it is a different problem altogether.

Are there any side effects?

Although side effects are very rare, they may include the following:

• Flare response

  Steroids may cause pain, swelling, redness and warmth in the injected area in up to 25% of patients. This can also present as facial flushing. Paracetamol and/ or Non-steroidals such as Ibuprofen can be taken to settle this. If it is unmanageable, it is advisable to seek medical attention from your GP or urgent care centre

• Bleeding

  Although rare, it is possible the injection site may continue to bleed. The bleeding should stop if pressure is applied the site. Taking blood thinners such as aspirin or warfarin can affect this

• Skin changes

  Very rarely (2-4% of patients), the skin near the injection site may discolour, leave a dimple and became sensitive to light (photosensitivity). This usually settles after a few months but can be permanent in some

• Infection

  It is possible for the injected area to become infected. Signs to look out for are the area becoming red, hot, swollen, discharging pus or you start feeling unwell with a temperature. The chances of infection are around 1 in 20,000 but if you suspect this might be happening then you need to see a Doctor urgently
