Injection Therapy

Injection Therapy

My surgeon has prescribed injection therapy. What will this injection do?
An injection in to the appropriate area will suppresses inflammation in the tissue and will help to combat any musculo-skeletal pain you may have.  Many patients obtain lasting relief of symptoms from injection therapy.

What is in the injection?

The injection is comprised of 2 ingredients, these being a local anaesthetic called Marcaine which is used to aid the diagnosis and diminish pain, and a slow release steroid called Depo-Medrone which is an anti-inflammatory medication used to reduce swelling.

What should I do or expect after the injection?

The anti-inflammatory effect of your injection therapy will start 24 to 36 hours after treatment and will continue to work for up to 3 weeks giving long-lasting benefit.

You are advised not to undertake the sport or repetitive activity that caused your problem for 1 week after your injection.  You may require physiotherapy to prevent recurrence or your problem and you should seek advice if you are at all concerned

Will I need to attend any follow up appointments?

You will be seen in an Out Patient clinic approximately 6 weeks after your procedure.  This appointment will be made for you before you leave the hospital after your injection therapy. The amount of physiotherapy you require will be dependent on your progress.

I have been informed that there may be some side effects. What are they?

The most common side effects include what is known as a post injection flare. This means that you may experience a temporary worsening of pain and sometimes a little swelling and local heat.  This is quite a rare reaction resulting from the anti-inflammatory component of the injection.  The flare is temporary and will settle quickly if a non-steroidal anti-inflammatory drug such as Ibuprofen, or analgesia like Paracetamol is taken.  An ice pack over the area may also help. Some facial flushing or reddening of the face may very occasionally occur but this usually only lasts 24 to 48 hours and is not uncomfortable. Very rarely some women make experience an irregular period as a result of the steroid component. Skin changes such as a slight discoloration and thinning of the skin may also occasionally occur locally at the site of the injection.

You will need to be aware of a number of very rare side effects that can occur after injection therapy. If you are a diabetic you may experience a passing upset of your glucose control and it is important to monitor your sugar levels for up to 2 weeks after your injection. If the area becomes hot and swollen you may have picked up an infection and should contact your surgeon or GP as soon as you can. In very rare cases a tendon may rupture as a result of the injection. Again, if this occurs you must contact your surgeon or GP as a matter of urgency. Finally, in very rare circumstances you may have an allergic reaction to the injection. Such a reaction would occur within minutes of the injection being administered and in such circumstances the medical team would treat you immediately.
