A corticosteroid injection (a "cortisone shot") is the right choice when an inflammatory or tendinopathic condition has not responded to first-line conservative care, when the diagnosis is reasonably confident, and when surgery is not yet warranted. The injection delivers a powerful anti-inflammatory medication directly to the source of pain in 5 minutes in the office. For the right condition at the right time, it can produce months of complete relief with minimal risk. For the wrong condition or for repeated use at the same site, the risks add up. This article explains how cortisone works, which hand and elbow conditions respond well, expected duration of relief, the risks, and how to think about injection versus surgery.

What a Cortisone Injection Actually Does

Corticosteroid medication (most commonly triamcinolone, methylprednisolone, or betamethasone) is a powerful anti-inflammatory. When injected directly into an inflamed joint, tendon sheath, or nerve compartment, it suppresses the local inflammatory cascade for weeks to months. Less inflammation around a tendon, nerve, or joint means less swelling, less pressure, and less pain.

The injection is not a painkiller in the traditional sense. It does not block nerve signals like a numbing medication. It changes the underlying biology of the inflamed tissue so that the source of pain settles. Because most hand and elbow problems involve a cycle where mechanical irritation produces inflammation that produces more mechanical irritation, breaking the inflammation can interrupt the cycle long enough for the tissue to recover.

Most injections in the hand and elbow are 1 to 2 mL total volume. The technique uses a small needle (25 or 27 gauge), and the injection itself takes about 30 seconds. Most patients walk out within 5 to 10 minutes of arriving in the procedure room.

Conditions That Respond Well

The hand and elbow conditions that respond predictably to corticosteroid injection:

Trigger finger: the gold-standard non-surgical treatment. Cure rates of 60 to 90 percent after 1 to 2 injections. Most patients have months to years of relief from a single injection.
De Quervain's tenosynovitis: 70 to 80 percent of patients have meaningful relief from a single injection. Sometimes a second injection at 6 to 12 weeks is needed for incomplete response.
Thumb CMC (basilar) arthritis: early-stage arthritis responds well, with 3 to 9 months of relief. As the arthritis advances, the duration of relief shortens.
Carpal tunnel syndrome: a useful diagnostic and bridging tool. A positive response to a carpal tunnel injection helps confirm the diagnosis and predicts a good surgical outcome. Duration of relief averages 2 to 6 months.
Tennis elbow and golfer's elbow: short-term relief (6 to 12 weeks) is reliable but the injection does not change the long-term course of the tendinopathy. Best used to break a severe flare so the patient can engage in eccentric exercise therapy.
Ganglion cysts: aspiration with cortisone injection has a 30 to 50 percent cure rate in dorsal wrist ganglion cysts.
Wrist osteoarthritis (early stages): intra-articular injection of the wrist or specific joints can give months of relief.

Conditions That Do Not Respond Well

Some hand and elbow problems do not respond to corticosteroid injection and should be approached with other treatments:

Advanced cubital tunnel syndrome (ulnar nerve at the elbow) with constant numbness, weakness of grip, or muscle atrophy. Once nerve damage has progressed, injection rarely changes the trajectory.
Complete tendon ruptures. A torn tendon needs surgical repair, not steroid medication.
Advanced arthritis with bone-on-bone changes at the CMC, wrist, or finger joints. Injections become less effective and shorter-acting as the joint surface degenerates.
Carpal tunnel with constant numbness, thenar atrophy, or significant weakness. Injection may give brief relief but the underlying nerve damage continues. Endoscopic release is the right move.
Nerve tumors, ganglions in unusual locations, and any mass with red flags. Imaging or biopsy first; injection later if appropriate.
Suspected infections. Cortisone in an infected space can dramatically worsen the infection. Always evaluate first.

What to Expect During and After

The injection itself is brief. Skin is cleaned, a small needle is placed, and the medication is delivered. Most patients describe a brief stinging or pressure sensation that lasts seconds to a minute.

The first 24 to 48 hours after the injection often include a "steroid flare," where the tissue reacts to the medication and the area feels more sore than before. This is normal and expected. Ice and over-the-counter anti-inflammatory medication help. The flare typically settles by day 3.

The therapeutic effect kicks in between days 3 and 7. By the end of the first week, most patients with a responsive condition feel significant improvement. The improvement typically increases through week 3 and stabilizes from there. Duration of relief depends entirely on the condition.

Activity restrictions are usually limited: avoid heavy lifting or vigorous use of the injected area for the first 48 hours. After that, normal activity is fine.

The Risks

Cortisone injections are very safe when used in the right indication and at appropriate intervals. The known risks include:

Steroid flare in the first 24 to 48 hours: common, mild, and self-limited.
Skin discoloration at the injection site: light or hyperpigmented patches that gradually fade over months. More common in patients with darker skin and at superficial injection sites (trigger finger, tennis elbow).
Subcutaneous fat atrophy: a small dimple or depression at the injection site from local fat loss. Permanent in some cases. More common with multiple injections at the same superficial site.
Tendon weakening with repeated injections: corticosteroid weakens the tendon over time. The risk of rupture is low but not zero. This is why we limit injections at the same site.
Transient blood sugar elevation in patients with diabetes: 1 to 2 weeks of higher fasting glucose after a hand or elbow injection. Worth knowing but rarely a clinical problem.
Infection: extremely rare with sterile technique, but worth knowing.
Injection failure: 20 to 40 percent of patients (depending on condition) do not respond to the first injection. A second injection sometimes succeeds where the first failed.

The 2-to-3 lifetime injection guideline at a single site exists because tendon weakening, fat atrophy, and skin changes accumulate with repeated injections. After 2 or 3 injections at the same site, the risk-benefit balance tips toward considering surgery instead of more injections.

Choosing Injection Versus Surgery

The right framework for thinking about this decision:

For mild to moderate, episodic problems (early trigger finger, mild De Quervain's, mild carpal tunnel): injection is almost always the first move. Many patients never need surgery.
For problems that have failed injection (recurrent trigger finger after 2 cortisone shots, carpal tunnel symptoms returning within weeks of an injection): surgery is the right next step.
For problems with permanent damage already present (atrophy, contracture, locked finger that cannot be passively straightened): surgery directly, with no injection trial.
For patient priorities: a patient who has a wedding in 3 weeks may prefer an injection to break a flare even knowing surgery is likely needed eventually. A patient who has had multiple injections without lasting relief may prefer surgery to settle the issue.

Cortisone is a powerful tool when used in the right situation. Used too often, in the wrong condition, or in place of an indicated surgery, it does not serve the patient well. The decision should always involve a clear discussion of expected duration of relief, what comes after the injection wears off, and what the alternative looks like.

Frequently Asked Questions

Does the injection itself hurt?

Most injections are quick and tolerable. The needle stick and the initial spread of the medication produce a brief stinging or pressure sensation that lasts seconds to a minute. Some injections (the thumb CMC joint, the carpal tunnel) are more uncomfortable than others (trigger finger, De Quervain's). Local anesthetic is mixed with the corticosteroid in many injections, which makes the spot feel numb within minutes. The most common pain pattern is a flare during the first 24 to 48 hours as the body reacts to the medication, followed by significant relief starting on day 3 to 5.

How long does relief usually last?

Duration depends heavily on the condition. Trigger finger injections often produce 3 to 12 months of complete relief, sometimes lasting indefinitely. De Quervain's tenosynovitis injections often produce 3 to 9 months of relief. Carpal tunnel injections give 2 to 6 months on average and serve more as a diagnostic and bridging tool than a long-term solution. Thumb CMC arthritis injections give 3 to 9 months early in the disease but produce shorter and shorter relief as the arthritis advances. Tennis and golfer's elbow injections often produce 6 to 12 weeks of relief but do not change the long-term course of the tendinopathy.

Why do you limit injections to 2 or 3 at the same site?

Repeated corticosteroid injections at the same anatomic site can weaken the local tissue. The most concerning effects are tendon weakening (which can lead to rupture, especially in the flexor tendons of the hand), thinning of the skin, fat atrophy under the skin (which leaves a small dimple), and skin discoloration. These risks are very low with one or two injections and increase significantly with three or more at the same site within a 12-month period. The 2-to-3 lifetime limit at a single site is a safety guideline that balances the benefit of additional injections against accumulating tissue effects.

When should I pick injection versus surgery?

Injection is the right first choice for trigger finger, De Quervain's, mild carpal tunnel, early thumb CMC arthritis, and tennis or golfer's elbow that has not responded to bracing and therapy. Surgery becomes the right choice when injections have failed (no relief or quickly returning symptoms despite a previous good response), when the condition has progressed beyond what medication can manage (advanced arthritis, severe nerve compression with weakness or atrophy, complete tendon ruptures), or when the patient prefers a more durable solution to repeated injections. The decision is shared between the patient and the surgeon based on symptom severity, prior treatment response, and lifestyle priorities.
