What You Need to Know Before You Apply

What is the purpose of this trial?

A procedure frequently performed by orthopaedic providers is the administration of corticosteroid injections for the management of various soft tissues and joint-related conditions, such as osteoarthritis, tendinitis, carpal tunnel syndrome, trigger finger, and de Quervain's tenosynovitis. While these injections have demonstrated effectiveness in alleviating symptoms, the discomfort associated with the procedure can be a source of anxiety and apprehension for patients. This discomfort arises from the sensation of the needle entering the affected area and the burning sensation induced by the corticosteroid solution.

Are You a Good Fit for This Trial?

This trial is for individuals getting their first corticosteroid injection in an arm or leg, including soft tissue and joint injections. It's aimed at those who may have a fear of doctors, needle phobia, or concerns about pain management.
