A cortisone shot often starts helping within 24 to 72 hours, but the full effect may take up to a week and sometimes longer. If your injection included a local anesthetic, you may feel early relief for a few hours; that early change can fade before the corticosteroid effect develops. A cortisone shot is a targeted corticosteroid injection used around a joint or soft tissue to reduce inflammation and pain.
How quickly it helps depends on the area treated, the cause of your pain, and your own response. Ask the clinician who performed the injection what timing makes sense for the specific joint, tendon, bursa, or nerve-related symptom they treated.
What is a cortisone shot meant to do?
Cortisone is a corticosteroid, a medicine that can calm inflammation in a focused area. Clinics use these injections around joints and soft tissues for problems such as arthritis-related joint pain, bursitis, and tendon irritation. Some injections also contain a local anesthetic, which can numb the area for a short time.
The reason for the injection matters. NIAMS explains osteoarthritis as a condition in which joint tissues break down over time; it can involve pain, stiffness, swelling, and reduced movement. Back pain also has many possible causes, including disc, muscle, joint, and nerve problems, as NIAMS describes in its back-pain guide. A shot aimed at inflammation may fit one cause of pain better than another.
What is the usual cortisone-shot timeline?
| When | What you may notice | What it can mean |
|---|---|---|
| Right after the injection | Short-term numbness or easier movement | If local anesthetic was used, it may be causing the early relief. |
| First 1 to 2 days | Soreness or a temporary increase in pain | This is often called a steroid flare. The injection itself can irritate the area for a short period. |
| About 24 to 72 hours | Less pain, stiffness, swelling, or easier movement | Ramsay Health Care says many people begin to notice improvement in this range. |
| Up to a week | A clearer sense of whether the injection is helping | Ramsay Health Care says the full effect can take up to a week. |
| Weeks to months | Relief may continue, fade, or be limited | Duration varies with the condition, tissue involved, and individual response. |
There is no single deadline that applies to every injection. The treatment area, the level of inflammation, and whether pain is coming from the injected structure all change the timeline. A procedure page from New Jersey Brain and Spine also describes relief as temporary rather than permanent.
How do you know whether the cortisone shot is working?
Look for a practical change in the problem your clinician was trying to address. That might be less pain with a familiar movement, less stiffness after rest, less swelling, or better ability to sleep, walk, reach, or use the joint. Keep the comparison simple: note what you could do before the injection and what you can do after the expected onset window.
Immediate numbness is not the same as the longer anti-inflammatory effect. If pain returns after the numbing medicine wears off, that does not by itself tell you the corticosteroid has failed. The more useful check is what changes over the following days and the time frame your clinician gave you.
What should you avoid after a cortisone shot?
Aftercare should follow the instructions for your injection site. Ramsay Health Care advises resting the treated area for 24 to 48 hours and avoiding strenuous activity, heavy lifting, and high-impact exercise during that period. The same page says many people return to regular activity within a couple of days, sometimes with a gradual return to movement as part of a broader plan.
Ask before you leave whether driving is suitable after your particular injection, when to resume work or exercise, and whether the plan includes rehabilitation or follow-up. Those answers can differ for a knee, shoulder, spine, hand, foot, tendon, or bursa injection.
Why might a cortisone shot not help?
A limited response can have several explanations. The source of pain may not be the structure that was injected. The problem may involve more than inflammation. The condition may be longstanding, or the affected tissue may respond differently than expected. A shot can also reduce inflammation without changing every contributor to pain or reduced movement.
This is why diagnosis matters before comparing treatments. For nerve-related symptoms such as burning, tingling, numbness, or weakness, NINDS explains peripheral neuropathy as a group of conditions involving disrupted nerve signaling, with many possible causes. A clinician can help determine whether an injection is aimed at the likely pain source.
What if pain gets worse after the injection?
Some people have a short-lived pain increase after an injection, often called a steroid flare. Joint Injections says temporary soreness, bruising, or increased pain can happen after the procedure. It also says to seek medical advice if pain becomes severe or keeps worsening, or if you have increasing redness, warmth, swelling, fever, or feel unwell.
Ask your clinician what symptoms should prompt a call for your specific procedure, especially if you have other health conditions or take regular medicines.
Where does a cortisone shot hurt the most?
There is no one “most painful” injection site for everyone. Discomfort can depend on the size of the space, nearby sensitive structures, how inflamed the area is, the depth of the injection, the use of local anesthetic, and your own sensitivity. Joint Injections notes that hands, wrists, feet, and ankles can feel more sensitive because they contain many small structures in confined areas. Larger joints can feel different, but location alone cannot predict your experience.
Your clinician can explain what the specific injection may feel like and whether image guidance or local anesthetic is part of the plan.
What is the next step if a steroid injection does not work?
The next step is usually a review of the diagnosis, the injection target, your response, and the options that fit the condition. That may include a different rehabilitation plan, another form of pain management, further assessment, or a discussion of procedures. It is not automatically another injection.
If you are considering a procedure conversation, bring a written record of your symptoms, prior treatments, medicines, and the exact result from the injection. Our guide to procedure conversation questions can help you organize the questions that matter before a visit.
Is there something better than a cortisone shot?
There is no single replacement shot or “natural” option that is better for every kind of pain. The best comparison starts with the diagnosis and your goal: short-term pain relief, easier movement, a longer rehabilitation window, or evaluation of a different cause.
For chronic pain, NCCIH’s chronic-pain overview says research supports some non-drug approaches for some painful conditions, including acupuncture, yoga, tai chi, massage, mindfulness-based approaches, and spinal manipulation. The strength of research varies by condition. For example, NCCIH reports that tai chi is strongly recommended in a guideline for knee or hip osteoarthritis, while evidence for massage in hip or knee osteoarthritis is weaker.
“Natural” does not automatically mean safer or more suitable. NCCIH notes that dietary supplements can have side effects and interact with medicines. For knee osteoarthritis, its review of glucosamine and chondroitin finds inconsistent study results and differing professional-guideline recommendations. A new injection or regenerative-medicine option also deserves the same careful questions about the diagnosis, expected benefit, follow-up, cost, and what the clinician will measure.
For a clearer way to judge research claims about an emerging procedure, read how to read a trial record. A clinical trial is a study in people that tests a health intervention and records planned outcomes; the record can show who was studied and what researchers intended to measure.
Do you really need a cortisone shot?
You may not need one simply because pain is persistent. A cortisone shot is one option when a clinician believes inflammation in a particular area is contributing to your symptoms and the potential benefit fits your situation. It can be part of a broader plan rather than the whole plan.
The decision is more useful when you know what the shot is intended to change, how long you should wait to judge it, what other options are reasonable, and what happens if it does not help. If you are weighing a regenerative-medicine procedure as well, our guide to trial follow-up periods explains why duration of follow-up matters when you are considering longer-term questions.
Questions to ask before you decide
- What structure do you think is causing my pain, and why?
- What medication is in this injection, and is a local anesthetic included?
- When should I expect to notice a change for this specific injection site?
- What should I avoid for the first 24 to 48 hours?
- What symptoms after the injection should prompt me to contact you?
- How will we decide whether it worked?
- If it does not help, what diagnosis or treatment options should we discuss next?
- What are the realistic alternatives for my condition, including rehabilitation and non-drug options?
