The Cortisone Shot That Feels Good Now and Costs You Later

Does cortisone make tennis elbow worse?

For tennis elbow specifically, the evidence points one direction: a cortisone shot tends to trade a few good weeks for a worse year. In the strongest randomized trial, people who received a corticosteroid injection were doing worse at one year — and were more likely to have their pain recur — than people who received a placebo injection 1Ref 1Coombes BK, Bisset L, Brooks P, Khan A, Vicenzino B (2013).Effect of Corticosteroid Injection, Physiotherapy, or Both on Clinical Outcomes in Patients With Unilateral Lateral Epicondylalgia: A Randomized Controlled Trial.For tennis elbow, corticosteroid injection produced worse one-year outcomes and higher recurrence than placebo injection, while the placebo group recovered over the year.. The early relief is real. So is the later cost, and the later cost is the part that usually gets left out of the decision.

That is a genuinely surprising result, because the shot works exactly as advertised in the short term. Within a week or two the pain often falls sharply, which feels like proof the injection is fixing the problem. The one-year data say otherwise: the same people are, on average, no better off and frequently worse off than if they had left the elbow alone. For tennis elbow, the fastest relief and the best year are not the same choice. The question worth asking is not whether the shot helps this week, but where it leaves you twelve months from now.

Why the early relief is misleading

The reason a cortisone shot can backfire has to do with what tennis elbow actually is. Despite the '-itis' in its old name, the condition is less a fire of inflammation than a failure of the tendon to repair itself — a degenerative tendon problem, or lateral epicondylitis, in which the tissue at the outside of the elbow has broken down faster than the body rebuilds it. A steroid calms the pain signal, but it does not rebuild tendon, and it may blunt the very repair process the tendon needs.

That pattern — strong short-term relief, no durable benefit — is not unique to the elbow. Epidural corticosteroid injections for sciatica show the same shape: a small, short-term reduction in leg pain, then no meaningful long-term advantage and no reduction in later surgery 2Ref 2Pinto RZ, Maher CG, Ferreira ML, et al. (2012).Epidural Corticosteroid Injections in the Management of Sciatica: A Systematic Review and Meta-analysis.Epidural corticosteroid injections for sciatica give small, short-term relief with no meaningful long-term benefit and no reduction in later surgery — the same short-term-only pattern seen with steroid injections.. Steroids are good at quieting symptoms for a while. They are much less reliable at changing where a problem ends up, and in some tissues the temporary quiet appears to come at the price of a slower recovery.

This is about tennis elbow, not injections in general

None of this makes cortisone injections a bad idea everywhere — the story is condition-specific, and treating it as a blanket rule gets it wrong in the other direction. For osteoarthritis of the hand, hip, and knee, major guidelines conditionally recommend an intra-articular corticosteroid injection for short-term relief, precisely because in that setting the trade-off can be worth it 3Ref 3Kolasinski SL, Neogi T, Hochberg MC, et al. (2020).2019 American College of Rheumatology/Arthritis Foundation Guideline for the Management of Osteoarthritis of the Hand, Hip, and Knee.For hand, hip, and knee osteoarthritis, guidelines conditionally recommend intra-articular corticosteroid injection for short-term relief, showing that injections have a legitimate, condition-specific role.. The same drug, in a different problem, earns a place.

What does travel across conditions is caution about repetition. When steroid injections are given over and over, the ledger shifts: in a two-year trial of repeated knee injections, the shots produced no better pain relief than salt water and were associated with greater loss of cartilage 4Ref 4McAlindon TE, LaValley MP, Harvey WF, et al. (2017).Effect of Intra-articular Triamcinolone vs Saline on Knee Cartilage Volume and Pain in Patients With Knee Osteoarthritis: A Randomized Clinical Trial.Repeated intra-articular corticosteroid injections over two years gave no better pain relief than saline and were associated with greater cartilage loss, supporting caution about repeated injections.. That is really a separate question — how many cortisone shots are safe before diminishing returns and cartilage harm set in — from whether any single shot helps a given condition. So the honest summary is not 'cortisone is harmful' but something narrower: whether a shot helps depends on the condition, repetition carries its own cost, and for tennis elbow in particular the balance tips against it for most people, most of the time.

What tends to work better over the year that matters

Left alone, most tennis elbow gets better — slowly. The placebo group in that landmark trial is the tell: people who got a dummy injection and simply let time pass ended up ahead of the steroid group at a year 1Ref 1Coombes BK, Bisset L, Brooks P, Khan A, Vicenzino B (2013).Effect of Corticosteroid Injection, Physiotherapy, or Both on Clinical Outcomes in Patients With Unilateral Lateral Epicondylalgia: A Randomized Controlled Trial.For tennis elbow, corticosteroid injection produced worse one-year outcomes and higher recurrence than placebo injection, while the placebo group recovered over the year.. Tennis elbow healing time is measured in months, not weeks, and the natural history of lateral epicondylitis is frustratingly patient, but it bends toward recovery for the large majority.

What helps that natural course along is load, not rest — gradually reintroducing demand to the tendon under guidance, so it is nudged to rebuild. Starting with conservative care also tends to be efficient. Episodes of physical therapy begun by direct access, without first routing through a referral, have been linked to fewer visits, less imaging, less medication, and lower costs, with no worse outcomes 5Ref 5Ojha HA, Snyder RS, Davenport TE (2014).Direct Access Compared With Referred Physical Therapy Episodes of Care: A Systematic Review.Physical therapy episodes begun by direct access were associated with fewer visits, less imaging and medication, and lower costs without worse outcomes than referred care.. For a condition that mostly resolves on its own, the goal of early care is less to force healing than to protect the tendon from setbacks and keep you using the arm while time does its work.

That is the sequence-of-care logic: try the low-risk, low-cost measures that fit a self-limiting condition first, and reserve the interventions with real downsides for when they are genuinely needed.

When a cortisone shot is still a reasonable choice

A cortisone shot for tennis elbow is not never — it is a specific tool for a specific moment. When pain is severe enough to wreck sleep or make work impossible, and when someone understands that the injection buys short-term relief at the likely cost of a worse one-year outcome, choosing it as a deliberate bridge is a reasonable, informed decision. The problem comes when it is offered as a first move and a cure, rather than as a limited-purpose, usually one-time step.

Escalation beyond conservative care also has a legitimate place. If disabling symptoms persist despite a genuine trial of guided loading and time — often on the order of six to twelve months — that is the point to revisit the plan with a specialist and weigh other options, including procedures. The tennis elbow treatment decision is best made in that order: conservative care first, a candid look at a shot's real trade-off if a bridge is truly needed, and further intervention reserved for the minority who do not turn the corner. Surgery is not the villain here any more than the shot is; it is simply further down a sequence that most people never have to complete.

When elbow pain should be examined, not injected

Some elbow pain should be looked at rather than injected, because it is not tennis elbow at all. Pain on the inside of the elbow rather than the outside points toward golfer's elbow, and telling tennis vs golfer's elbow apart changes the plan; pain with tingling into the ring and little fingers suggests a nerve rather than a tendon; and a hot, swollen, feverish elbow is a different problem entirely.

The cost side is worth knowing too, since it quietly shapes decisions. A cortisone injection is often inexpensive up front, which can make it feel like the low-stakes option — but the cortisone injection cost that matters for tennis elbow is measured in the year afterward, not on the day of. Before reaching for a needle, it is worth confirming the diagnosis, since a shot aimed at the wrong problem cannot help and may still carry the tendon-specific downside. When the picture is unclear, an examination answers more than an injection does.
