Yes, you will usually be asked to rest the joint or soft-tissue area after a cortisone injection, often for a few days. The exact plan depends on where the injection went, whether it included local anaesthetic, and what you need that joint to do. The NHS says people may need to rest the treated joint for a few days, while the 2023 McMorrow review recommends one to two days of relative rest before a gradual return to sport after an injection into a joint.
What is a cortisone shot, and why can you feel better quickly?
A cortisone shot is an injection of a corticosteroid, a medicine that can reduce inflammation. It may be placed in or around a joint, tendon, or bursa, which is a small fluid-filled cushion near a joint. Cleveland Clinic’s cortisone-shot guide says providers use these injections for inflamed joints, tendons, and bursae, including in the shoulder, hand, hip, knee, and foot.
Some injections also contain a local anaesthetic. That numbing medicine can explain why you feel good right away. The steroid itself may take longer. The Royal Orthopaedic Hospital says many people notice improvement within 24 to 48 hours, but for some people it takes days to weeks. Cleveland Clinic says relief can take up to a week.
How much rest do you need after a cortisone injection?
Think in terms of relative rest: giving the injected area a break from strenuous loading, not necessarily staying in bed. The clinician who performed your injection should give you the plan that fits your joint, diagnosis, work, and activity.
| Situation | What the supplied guidance says |
|---|---|
| General joint or tendon injection | The NHS says you may need to rest the treated joint for a few days. |
| Return to high-demand sport | The McMorrow review recommends one to two days of relative rest, followed by a progressive return. This is Level V evidence, meaning expert opinion rather than a high-quality trial. |
| First hours after an injection with local anaesthetic | The Royal Orthopaedic Hospital advises not driving for a few hours after an injection involving local anaesthetic. |
| Strenuous exercise | The Royal Orthopaedic Hospital advises resting the area and avoiding strenuous exercise for a few days, then building activity gently. |
For a knee, walking may be part of normal daily life, but the amount that makes sense for you depends on the reason for the injection and your clinician’s instructions. The same is true for a hand, shoulder, or hip injection: the treated body part and the activity matter more than a one-size-fits-all rule.
What happens if you do not rest after the injection?
The best direct research is limited and mixed. The 2023 McMorrow review discusses a randomized study of people receiving a knee injection: it compared 24 hours of rest with no rest after triamcinolone and lidocaine. At three weeks, the groups did not differ. From 12 to 25 weeks, the rested group had greater improvement in pain, stiffness, knee size, walking time, and C-reactive protein, a blood marker of inflammation. Another study in the review found no benefit from rest at 48 hours or at 10 months when it measured pain, swelling, motion, and overall status.
That is why the review’s one-to-two-day recommendation is practical guidance, not a settled rule for every person or every injection. Its authors also note that research on early high-intensity activity is limited. Use Written Aftercare Information to compare the instructions you receive with the questions that matter for your own procedure.
What should you avoid, and can you drive?
Your aftercare sheet should name the movements that load the treated area. The Royal Orthopaedic Hospital advises avoiding strenuous exercise for a few days and then increasing activity gently. For a knee or hip, that may matter for impact exercise or heavy loading. For a shoulder or hand, it may matter for lifting, gripping, or repeated overhead work.
Driving is a separate question. If local anaesthetic was used, the Royal Orthopaedic Hospital advises not driving for a few hours. Ask before the appointment whether your injection will include local anaesthetic and whether your injection site changes the driving plan. If you may need assistance getting home, this Helper Planning Guide can help you plan ahead.
Why is the injection still painful a week later?
A temporary increase in pain can happen after an injection. The McMorrow review calls this a steroid flare: pain and discomfort at the injection site and in the treated joint. It reports that flares commonly begin within 24 hours, with some beginning 24 to 48 hours later, and estimates reported rates at 1% to 10%, depending on the medicine, dose, and route.
A week of pain does not have one universal explanation. Cleveland Clinic says to contact your provider if pain and inflammation are still present more than 10 days after the injection. It also lists intense pain, fever, or worsening swelling as reasons to contact a provider. The Royal Orthopaedic Hospital lists increasing redness, warmth, pain, or fever as symptoms that need same-day medical attention.
Can fatigue or other side effects happen?
Side effects depend on the medicine, dose, injection site, and your health history. Cleveland Clinic lists injection-site pain, temporary swelling, bruising, temporary blood-sugar increases, skin color changes, infection, fluid retention, and high blood pressure among possible effects. The Royal Orthopaedic Hospital also lists temporary facial flushing, mood changes, and menstrual-cycle changes. If you feel unusually fatigued after an injection, ask the clinician who performed it how they want you to handle that symptom, especially if it comes with other changes that concern you.
People with diabetes may need a specific blood-sugar plan. Cleveland Clinic says steroid shots can temporarily raise blood sugar and that people with diabetes should check it more often for about five days. Bring a current list of medicines and supplements to the appointment. The Royal Orthopaedic Hospital specifically identifies bleeding tendency, certain medicines, infection, recent joint trauma, pregnancy or breastfeeding, and planned surgery as topics to discuss before an injection.
Are cortisone injections worth having?
They can be a useful option when inflammation is part of the problem and the expected benefit fits your goals. Cleveland Clinic describes them as a way to deliver corticosteroid directly to an inflamed area and says effects often last weeks to months. The NHS says hydrocortisone injections usually help pain and swelling for around two months, but individual results vary.
Whether one is worth having depends on the diagnosis. For example, NIAMS’s osteoarthritis guide explains that osteoarthritis involves changes across the joint, including cartilage, bone, tendons, ligaments, and the joint lining. A shot may be one part of managing symptoms; it does not answer every cause of joint pain. Your clinician can explain what structure they are targeting and what result would count as a useful outcome for you.
Is there a better shot than cortisone?
There is no single replacement shot that is better for every painful joint, tendon, or nerve-related symptom. The best comparison starts with the source of your pain and what you want to be able to do. For chronic pain more broadly, the NCCIH chronic-pain overview says research suggests some approaches, including acupuncture, mindfulness, tai chi, yoga, massage, and spinal manipulation, may help manage some painful conditions. The evidence and fit vary by condition.
If your question is about knee, hip, or hand osteoarthritis, ask which options fit that specific joint. NCCIH reports that tai chi is strongly recommended in an American College of Rheumatology and Arthritis Foundation guideline for knee or hip osteoarthritis. It also reports that research on glucosamine and chondroitin has produced inconsistent results, and guideline recommendations differ. A comparison should be about your diagnosis, not a promise that one injection or supplement will suit everyone.
How many cortisone shots can you have?
There is no lifetime number that applies to everyone. The NHS says the number of hydrocortisone injections depends on the body area and dose strength. Cleveland Clinic says many people need to wait at least three months between rounds and that most people should not have more than three shots in a year. Ask your clinician to put their recommendation in writing for the specific joint or tissue being treated.
Repeated injections deserve a clear conversation. Cleveland Clinic notes that many rounds may increase osteoporosis risk. NIAMS’s osteoporosis guide explains that osteoporosis reduces bone strength and raises fracture risk, and it lists long-term glucocorticoid use among medicines that can contribute to bone loss.
Questions to ask before you leave
- What tissue or joint structure was injected, and what is the goal for this shot?
- How long should I rest this specific area, and which movements are off-limits?
- Was local anaesthetic used, and when is it safe for me to drive?
- When can I return to walking, work, exercise, lifting, or sport?
- What level of pain or swelling is expected, and what symptoms mean I should contact you that day?
- How many injections in this area do you recommend, and how far apart?
- What are the non-injection options for my diagnosis?
Bring these questions to your visit and use the Recovery Planning Guide to record the answers before you make activity plans.
