Corticosteroid (cortisone), are hormones located within the body and are responsible for the regulation of inflammation, metabolism, immune function, as well as salt and water balance. When a joint/soft tissue becomes inflamed and the body cannot respond to reduce the inflammation, steroid injections can be used to assist in reducing inflammation and swelling at the structure.
Steroid injection consists of small amount of corticosteroid that has an anti-inflammatory action and local anaesthetic which numbs the area temporarily. Injections into soft tissues and joints can be very effective in giving pain relief when the tissue is inflamed. It is known as a local injection because it acts only in that area and does not travel around the body.
A cortisone injection can be used at any point during a treatment plan but generally are used when conservative first line treatments such as footwear advice, stretching, low level laser therapy, mobilisation or bespoke orthoses have had only limited success.
Cortisone injections can be used on the following conditions
- Joint pain
- Plantar Fasciitis and other heel pains excluding Achilles Tendonitis.
- Sinus Tarsi Syndrome
The effect of the steroid is usually felt within 1 to 2 days but can be up to 10 days after the injection. The steroid provides up to six months of relief, however this duration is dependent on each patient.
