What are the risks?
The most common complication is an increase of pain immediately after the injection. This is called a flare and happens in around 10%injections. It is usually self limiting and treated with ice and analgesics.
The most serious risk is infection, particularly with injections into joints. This is extremely rare; various studies have estimated the risk at between 1 in every 14000 to 30000injections.
It is important to highlight that the injection does not always work. You may not see any relief, may only have temporary relief or only have partial relief of your symptoms.
Other complications include cartilage damage, tendon weakening or facial flushing.
After the injection
In most cases you should aim to have 24-48hours of relative rest. During this time youshould avoid strenuous or impacting exercise.
Where possible you should continue to doyour rehabilitation – the injection is tofacilitate, not replace this.
Mild pain and discomfort, provided you arefeeling well in yourself (no tiredness, fever orloss of appetite) can be treated with simplepain relief (Paracetamol) and/or low dose antiinflammatories(Nurofen, Voltaren).
More severe or worsening pain, stiffness,redness or swelling at or near the site ofinjection, as well as feeling generally unwell orfeverish may be due to an infection. Youshould seek urgent medical attention if thisoccurs.
