How It Works
Corticosteroids relieve pain and
inflammation.
A local anesthetic (lidocaine) may be used first to help with
diagnosis. If this shot improves the pain, then a corticosteroid injection is
given. Lidocaine is sometimes given with a corticosteroid to reduce the pain of
the injection.
Why It Is Used
Corticosteroid injection is sometimes used to treat
tennis elbow. Corticosteroids are given to relieve the
pain of tennis elbow when other forms of treatment haven't helped.
If you don't find long-term relief after a total of three
injections over the course of a year, more injections aren't likely to help and
may cause harm.
Some doctors believe that corticosteroids should not be given to
children.
Corticosteroid treatment is not used when infection is
suspected.
How Well It Works
Studies suggest that corticosteroid injections may give short-term
relief but don't have long-lasting benefit when compared to other
treatments.1 One study found that, although
corticosteroid injection produced the most relief after 6 weeks, it was linked
to more relapse and pain after 52 weeks than treatment with rest and
rehabilitation.2
Side Effects
Corticosteroids are used with caution because of potential side
effects. Side effects may include:
- Increased pain the first day or two after a
corticosteroid injection. Applying ice at home for 15 to 20 minutes after the
injection may help reduce pain.
- Tendon weakening and scarring,
causing loss of strength and movement and potential for tendon
rupture.
- Accidental nerve injury during injection.
- Skin
color (pigmentation) changes.
- Dimpling of the skin (subcutaneous
atrophy).
- Infection.

What To Think About
Try using nonsurgical treatment (such as rest, rehabilitation
exercises, ice, and the use of nonsteroidal anti-inflammatory drugs) to relieve
pain and inflammation before considering corticosteroids.
There may be fewer side effects and less pain when corticosteroids
are given through iontophoresis. Iontophoresis is a drug delivery method that
uses an electrical current to move the drug through the skin into the tissue.
Because this method is less painful than hypodermic needle delivery, some
people may start rehabilitation sooner and experience faster pain
relief.3
