Knee injections can cause a brief pinch or sting during the procedure, but it's usually not severe, often made more comfortable with a local anesthetic to numb the skin. You can expect some soreness, stiffness, or aching for 24-72 hours afterward, which is manageable with ice and rest, but less severe than the underlying arthritis pain. Doctors use techniques like ultrasound guidance and numbing agents to minimize discomfort, making it a generally well-tolerated treatment, say this source.
Do cortisone shots hurt? A cortisone shot might sting when your provider puts the needle into your skin, but it shouldn't cause intense pain. Your provider might give you a local anesthetic to numb the area around the injection site. Tell your provider if you experience fear or anxiety about getting shots.
The injection is prepared. Usually, it contains a numbing agent in addition to the treatment. The doctor cleans the skin and typically applies a spray to numb the area. The doctor inserts the needle into the knee joint, often while using ultrasound or X-rays to guide the needle to the right location.
It is recommended that you refrain from any high level activities using your knee for approximately 48 hours. Routine activities including walking are permitted. The most commonly reported side effects are temporary pain, swelling and/or fluid accumulation in the injected knee.
Your knee may feel stiff or you may feel a spongy sensation when you walk. This may last for 2 to 3 days. You may not feel relief from your knee pain until after your last injection. You can put a cold pack on your knee for 10 to 15 minutes every 4 hours to help with any discomfort.
The most common side effect is mild pain and swelling at the injection site that goes away on its own. About 1% of people have a more severe reaction called an injection flare. It causes fluid to accumulate in the joint, with significant swelling and pain.
Areas with dense nerve endings or tight spaces, such as the sole of the foot (plantar fascia) or small joints in the hand, tend to be more uncomfortable. In contrast, larger joints like the knee, shoulder, or hip are generally less painful due to more room for the injection and fewer surface nerves.
Do not strain your knee joint for two days after receiving this medicine. Avoid activities such as jogging, soccer, tennis, heavy lifting, or standing on your feet for a long time. Temporary pain or swelling in the knee joint may occur after receiving hyaluronic acid injection.
Unfortunately, the results of gel shots are hard to predict. Some people have great outcomes, with pain relief that lasts for months. In other people, though, we don't see much improvement at all. Still, hyaluronic acid injections are approved for treating the knee joint, and are often covered by insurance.
For other types of joint injections (such as those in the knee, shoulder, or hip) pain relief may begin within 24 to 72 hours, particularly if a local anesthetic is used. Corticosteroids in these injections generally take 3 to 5 days to begin working, with maximum relief occurring in up to 10 days.
You don't usually need to make any special preparations before having a steroid injection. But it's best to wear comfortable clothes that allow easy access to the joint that will be injected.
The #1 mistake making bad knees worse is excessive rest and a sedentary lifestyle, leading to weaker supporting muscles, stiffness, and a vicious cycle of more pain; instead, gentle, consistent movement (like walking, swimming) is crucial to strengthen the joint and improve function, though it must be balanced with avoiding activities that cause sharp pain. Other major errors include ignoring pain signals, carrying excess weight, wearing unsupportive shoes, and poor movement patterns, says Parkside Sports Physiotherapy and Coastal Empire Orthopedics.
Depending on the site, average injection pain was 3.1–4.5 on a 10-point scale.
Are there effective non-steroidal alternatives to cortisone shots? Yes. Physical therapy, PRP injections, and non-invasive regenerative technologies such as SoftWave Therapy are commonly used when patients cannot receive steroids or have not experienced lasting relief.
No special preparation is required before a joint injection and you may eat and drink as normal. If you are taking blood thinners you must tell the receptionist when making your booking. This will allow the radiologist to assess whether it is safe to do the injection.
One is to spray a topical anesthetic over the site of injection. Another is to inject some anesthetic to numb it up.
Many of our patients with knee OA report from 6 to 12 months of pain relief after treatment with PRP. We usually see a 60% to 70% chance of success, with success defined as at least a 50% improvement in pain and function for 6 to 12 months after the injection.
Other non-surgical treatments: Depending on the back's condition and symptoms, other non-surgical treatments such as physical therapy, chiropractic care, acupuncture, or pain medication may be recommended.
After receiving a cortisone injection in your knee, most people can return to light walking and daily activities, although heavy physical exertion should be avoided for at least 48 hours.
Any Activity with a Fall Risk
Any activity, sport, or exercise that has a high fall risk should be avoided. Knee replacements lead to a heightened fall risk already, so keeping your risk low is very important.
Depending on your location and options, the out of pocket costs for knee gel injections can range from around $1,000 to $2,500 for a series.
20 most painful conditions
There's concern that repeated cortisone shots might damage the cartilage within a joint. So doctors typically limit the number of cortisone shots into a joint. The number can depend on the joint, the diagnosis and other factors.
Occasionally patients may get some discomfort the day after the injection when the local anaesthetic has worn off and before the steroid begins to take affect (normally from about 3 days following the injection). Usually this will be an achy pain and is generally well managed by use of an ice pack or hot water bottle.
