Steroid shots are most commonly given in joints like the knee, shoulder, hip, wrist, elbow, ankle, and spine, though they can also go into smaller joints in the hands and feet. When steroids are given for systemic (whole-body) effects rather than targeting a specific joint, they’re injected into large muscles like the upper outer buttock or the outer thigh. The exact spot matters: placing the needle in the wrong location can reduce the medication’s effectiveness or risk hitting a nerve.
Common Joint Injection Sites
Joint injections deliver the steroid directly into the space inside a joint, where it reduces inflammation at the source. The knee is one of the most frequently injected joints, and clinicians can approach it from several angles. The most common entry points are along the sides of the kneecap, either at the midpoint or just above it, with the leg straight. The needle slips into the gap between the kneecap and the underlying thighbone. Another option is entering just below and to the side of the kneecap near the joint line, with the knee slightly bent. A systematic review identified eight distinct knee injection sites, and the choice depends on factors like swelling location and the patient’s anatomy.
Shoulder injections typically target the space just below the bony shelf at the top of the shoulder (the acromion). The standard approach enters from the back and side: the needle goes in just below the rear outer corner of that bony shelf and angles forward. This is the go-to site for conditions like rotator cuff irritation and bursitis.
Hip injections usually require imaging guidance because the joint sits deep beneath layers of muscle. Wrist injections are common for carpal tunnel syndrome, but precision is critical. The nerve that runs through the carpal tunnel sits only about 8 millimeters from the usual injection landmark, so clinicians use specific tendon positions as guides to avoid it. Injections placed in the wrong spot carry roughly a 2% risk of nerve injury.
Smaller joints in the hands and feet can also receive steroid shots for conditions like arthritis or trigger finger. Elbow injections often target the area around the outer bony bump for tennis elbow, or directly into the joint for arthritis. Spinal injections, such as epidurals, are performed under imaging guidance and target the space around the spinal cord’s protective membrane.
Intramuscular Injection Sites
When a steroid is meant to work throughout the body rather than in one joint, it goes into a large muscle. The three main sites are the upper outer quadrant of the buttock (the gluteal muscle), the outer middle portion of the thigh (the vastus lateralis), and the deltoid muscle in the upper arm.
Research suggests the ventrogluteal site, located on the side of the hip rather than the back of the buttock, is the safest option. Unlike the other sites, it has not been associated with adverse effects in studies. The traditional dorsogluteal site (the back of the buttock) carries a risk of hitting the sciatic nerve if the injection lands too low or too far toward the center. Aiming for the upper outer quadrant helps avoid this.
The thigh’s outer middle muscle is a reliable alternative, especially for self-administered injections, since it’s easy to see and access. The deltoid in the upper arm works for smaller volumes but poses some risk to the axillary nerve, which runs through the muscle. For most adults, a needle length of 1 to 1.5 inches is needed to reach the muscle properly, with longer needles for larger body types.
Anabolic Steroid Injections
For people prescribed anabolic steroids (testosterone or related hormones) for medical conditions, the injection sites overlap with those used for other intramuscular shots. The thigh and upper outer buttock are the two primary locations. The deltoid is sometimes used but is not ideal for oil-based steroid formulations, which are thicker and need a larger muscle to absorb properly.
Site rotation is essential. Injecting the same spot repeatedly can cause scar tissue buildup, making future injections more painful and less effective. Alternating between the left and right thigh, and between thighs and buttocks, gives each muscle time to recover.
Why the Exact Spot Matters
Placing a steroid shot in the right location isn’t just about effectiveness. Injecting too superficially, into the fat layer instead of the joint or muscle, can cause localized side effects. Skin lightening (hypopigmentation) occurs in roughly 1 to 4% of patients who receive local steroid injections, and the tissue beneath the skin can thin or indent at the injection site. These cosmetic changes are usually temporary but can take months to resolve.
Nerve avoidance is another reason precision matters. In the wrist, the median nerve is vulnerable. In the buttock, the sciatic nerve is at risk. In the shoulder, the axillary nerve runs close to common injection paths. Clinicians use anatomical landmarks, and sometimes ultrasound guidance, to steer clear of these structures. Ultrasound-guided injections have become increasingly common for deeper or more complex joints like the hip, where blind placement is less reliable.
How Many Shots You Can Get
Most doctors limit steroid injections to three or four per joint per year. Beyond that, the pain relief tends to diminish with each additional shot, and the risk of complications rises. Repeated injections can weaken tendons and contribute to cartilage breakdown over time. If you’ve reached the annual limit without lasting relief, your provider will likely discuss other options, including surgery.
There’s no strict universal cap for intramuscular injections of systemic steroids, but frequency is still monitored because repeated courses can affect bone density, blood sugar, and other systems.
What to Do After the Injection
For joint injections, rest the area for at least 24 hours. This isn’t just about comfort. Exercise and joint movement can push the steroid out of the joint and into the bloodstream, reducing its local effect. The first day after the shot should involve minimal use of the injected joint.
After 24 to 48 hours, you can begin light, progressive activity. For a lower-body injection, that might mean cycling or bodyweight exercises before returning to full weight-bearing activity. Full return to sports or intense exercise generally happens within a few days, guided by how the joint feels. Even professional athletes are advised to take one to two days of relative rest before ramping back up.
Some soreness at the injection site is normal and can last a day or two. Ice and over-the-counter pain relief can help. A temporary increase in pain before the steroid kicks in, sometimes called a “cortisone flare,” is common and typically resolves within 48 hours.
