Shoulder Joint Injection

If you're experiencing shoulder pain, stiffness, or inflammation due to arthritis, injury, or overuse, a shoulder joint injection may be an effective non-surgical treatment option. This guide explains what a shoulder joint injection is, who it’s for, the benefits and risks, how to prepare, what to expect, and answers to frequently asked questions.

What Is a Shoulder Joint Injection?

A shoulder joint injection is a minimally invasive procedure where medication, typically a corticosteroid and/or local anesthetic, is injected directly into the shoulder joint. In some cases, hyaluronic acid or platelet-rich plasma (PRP) may be used depending on your condition.

Shoulder injections are commonly used to treat:

Osteoarthritis
Rheumatoid arthritis
Frozen shoulder (adhesive capsulitis)
Rotator cuff injuries or tendinitis
Shoulder impingement
Bursitis
Post-surgical inflammation
Labral or joint capsule inflammation

The goal is to reduce inflammation, relieve pain, and improve shoulder function.

Is a Shoulder Joint Injection Right for Me?

You may benefit from a shoulder injection if:

You have chronic or recurrent shoulder pain
You’ve been diagnosed with arthritis, bursitis, or tendinitis
You experience stiffness, swelling, or decreased range of motion
Medications, physical therapy, or rest haven’t been effective
You want to avoid or delay shoulder surgery
You’re experiencing a flare-up of shoulder symptoms

Benefits of Shoulder Joint Injections

Key benefits of shoulder injections include:

Direct relief of pain and inflammation
Improved mobility and shoulder function
Can be used to diagnose the source of pain
Quick, outpatient procedure
Minimally invasive and well-tolerated
May delay or reduce the need for surgery

Risks of Shoulder Joint Injections

Shoulder injections are generally safe, but possible risks include:

Temporary pain or swelling after injection
Infection (very rare with sterile technique)
Bruising or bleeding at the site
Tendon weakening or rupture with repeated steroid injections
Skin discoloration or thinning
Allergic reaction to medication (rare)
Post-injection flare-up (brief increase in pain for 24–48 hours)

Your provider will help you weigh the risks based on your health history and condition.

How to Prepare for a Shoulder Joint Injection

To prepare:

Let your provider know if you are taking blood thinners or have allergies, bleeding disorders, or active infections
No fasting is required
Wear a loose or sleeveless top to allow easy access to the shoulder
You may drive yourself to and from the appointment unless otherwise advised
Continue your regular medications unless directed otherwise

How Is a Shoulder Joint Injection Performed?

A shoulder injection is typically done in-office and may take about 10–15 minutes:

Positioning: You’ll be seated or lying down with the arm slightly supported
Cleansing: The injection area is cleaned with antiseptic
Local anesthetic: A numbing agent may be applied to reduce discomfort
Injection: A small needle is inserted into the joint space to deliver corticosteroid and/or anesthetic. Ultrasound or fluoroscopic guidance may be used for accuracy
Bandage: A small adhesive bandage is applied

Post-Procedure Care and Restrictions

After your shoulder injection:

Mild soreness or stiffness is common for 1–2 days
Apply ice to reduce any swelling
Avoid heavy lifting, overhead movements, or strenuous shoulder activity for 24–48 hours
Light activity is allowed unless otherwise directed
Monitor for signs of infection such as redness, warmth, or increasing pain
Your provider may recommend shoulder exercises or therapy to maintain mobility

How Long Will It Last? Will I Need More?

Pain relief can begin within a few hours to a few days
Effects may last from weeks to several months, depending on your condition and the type of injection used
Some patients require repeat injections, typically spaced at least 3 months apart
Repeated corticosteroid injections are usually limited to 3–4 per year per joint to avoid tissue weakening
