How do I prepare for an injection?

PRIOR TO YOUR APPOINTMENT DAY:

You do not need to do anything special before a joint injection. It IS important to drink plenty of fluids to stay hydrated.

The only exception is patients considering a platelet rich plasma (PRP) injection or an autologous blood injection. If you are considering either of these injection types, DO NOT take any anti-inflammatory medications (such as Naprosyn, Aleve, Advil, Motrin, ibuprofen, Celebrex, Feldene and diclofenac) 14 days before your injection appointment.

ON THE DAY OF YOUR APPOINTMENT:

Please bring a person who can give you a safe ride home. It varies from specific procedures but we do not recommend driving for at least 24 hours after an ultrasound-guided injection.

Please bring any previous x-rays, ultrasound, CT or MRI scans taken as part of your joint pain history.  Please tell the doctor or nurse if you are allergic to any medications. It may be best to wear comfortable clothing with easy access to the joint being injected.

What risks are associated with an ultrasound-guided injection?

This is a very safe procedure with few risks. There is a very low risk of infection, which probably lies between 1 in 10,000 to 20,000 patients. The procedure should not be performed if there is broken skin or infection overlying the joint or if the joint may already be infected.

There is a 1 in 10 chance of a steroid flare for all injections. This is when the pain worsens in the days following the injection, and it usually lasts about 3-5 days. This may indicate either an aggravation of the synovitis or very rarely an infection of the joint. If you experience increased pain, contact your referring doctor or the emergency department as soon as possible.

Side effects that may occur include facial flushing, nausea, swelling, redness, pain at the injection site, temporary numbness and weakness of the extremity, and skin discoloration. Side effects can last from 1-3 days.
