1.Infection (occurs in approximately 1 in 10,000 procedures). If the area injected becomes red, hot and swollen, and/or you feel feverish, it is important to seek medical advice immediately.
2.Bleeding into a joint or soft tissue. This is usually only a concern for people taking warfarin or similar anticoagulation (blood-thinning medicine).
3.Allergic reaction to the local anaesthetic.
4.When the area around a tendon or ligament has been injected, there is an extremely low risk of tendon rupture/tear. This most likely occurs due to overuse after the injection will assess the state of the tendon using the ultrasound scan before deciding whether to proceed with the injection.
Please bear in mind that your doctor has recommended you for this procedure because he/she believes that the potential benefits of the injection outweigh any potential complications. If you have any questions or concerns please do not hesitate to speak with your doctor.
What are the alternatives?
Alternatives to the injection include lifestyle changes, physiotherapy and oral pain relieving medication. Surgery may be an alternative option, which would need to be discussed with your specialist.
