Injection therapy usually is not recommended until a patient has undergone more conservative treatments designed to relieve symptoms of discomfort. This may include rest, anti-inflammatory and other analgesic medications, physical therapy and exercise to strengthen the muscles and increase flexibility. Injection therapy will be considered only if less invasive treatment methods fail to relieve a patient’s symptoms.

In preparation for injection therapy, imaging tests such as a CAT scan (computed axial tomography) or MRI (magnetic resonance imaging) may be performed to look at the area causing pain.

Prior to the procedure, patients may be asked to follow a number of preparatory steps. These may include avoiding the use of anti-inflammatory medications for a period of time. Depending on the type of injection, the patient may be told not to eat for a certain number of hours prior to undergoing the procedure. Some patients may be advised not to use anticoagulants (medications that reduce the clotting ability of blood), as these can increase the risk of bleeding during the procedure.
