Cortisone injections are often used to treat orthopedic conditions such as arthritis and tendonitis. Cortisone is a powerful medication that can help reduce swelling and inflammation. This, in turn, can decrease pain. Cortisone shots usually take effect in about five days.
Cortisone shots start to work very quickly. Still, it's different for each person. Some people report immediate relief and others say it takes a few days.
For some, it can take weeks for symptoms to improve. This article provides details about cortisone shots, how they work, and common side effects. Understanding these facts can help you know what to expect if you get a cortisone shot. Cortisone shots work by decreasing inflammation. In people with conditions like tendonitis, bursitis , and arthritis, pain is caused by inflammation.
Once the inflammation subsides, pain relief follows. A cortisone shot starts to work immediately. Inflammation usually improves within a few days. Pain relief can come within a few days to a few weeks, depending on how quickly the inflammation settles. Most people who have had a cortisone shot say the pain gets better over a span of days to weeks. The amount of inflammation, the type of injection , and other factors can all affect how quickly you feel relief.
If your inflammation is severe, or if it's been around a long time chronic , the shot may take longer to work. In some cases, you may need more than one dose.
Cortisone shots are effective for lots of common inflammatory conditions. But not all people respond to them. If your shot hasn't worked after a few weeks, let your healthcare provider know so you can discuss the next steps in treatment.

Your doctor or other healthcare professional might call these short-acting soluble steroids. Soluble means that the drug dissolves quickly in your body and starts working quickly. Other steroid injections take around a week to become effective but can ease your symptoms for two months or longer.
These are described as less soluble, because the drug takes longer to get into your system. Steroid injections can be given to people of all ages, including children and teenagers with juvenile idiopathic arthritis JIA.
However, steroid injections should be used with care in young people. Only the lowest effective dose should be given, and for the shortest possible time. Too much steroid treatment for children could affect their growth.
Your doctor or nurse will talk to you about the most appropriate steroid mixture and dose for you. This will depend on your condition and symptoms. They may want to check your blood pressure and blood sugar levels before your first injection as steroid injections can cause these to rise. They might delay the injection if either is raised. Most injections are quick and easy to perform.
You may need an ultrasound scan to find where the inflammation is, so the steroid can be injected into a precise spot and have maximum benefit. An ultrasound scan uses high-frequency sound waves to create an image of part of the inside of a body. Many injections can be given without the need for ultrasound.
This would mean your pain should be relieved within minutes. You may have some numbness from the anaesthetic that could last up to 24 hours. You might be advised to wait for 10 to 15 minutes in the clinic after your steroid injection. If you do have any kind of reaction to the injection, it would be helpful to be around healthcare professionals. For some conditions, such as inflammatory types of arthritis, steroid injections are often useful in the short term while you and your doctor find the right medications to control your arthritis in the long term.
In this case, once your arthritis is well controlled the need for injections should be reduced. It is important you monitor your blood sugar levels after a steroid injection. There is evidence that having too many steroid injections into the same area can cause damage to the tissue inside the body.
You may be advised to have less than that depending on your symptoms. There is a small risk that if you exercise a joint too much immediately after a steroid injection you could damage the tendon. The cortisone is delivered into the affected area with a thin needle. Cortisone is a type of molecule known as a corticosteroid, a precursor to the hormone cortisol. Cortisol is produced by your adrenal gland and plays many roles in your body, including suppressing the activity of your immune system.
Inflammation releases various substances, including the hormones bradykinin and histamine. These hormones irritate nerves and send pain signals to your brain. A cortisone shot reduces levels of molecules that stimulate inflammation. This can improve joint function and reduce stimulation of your nerves which leads to pain.
These shots often take effect within a few days , though some can be effective within a few hours, and can provide pain relief for up to several months depending on:. Cortisone and other corticosteroid shots are used to treat a wide variety of inflammatory conditions involving joints, muscles, or connective tissues.
Corticosteroid injections can cause short-term improvements in frozen shoulder and shoulder impingements. A study in American Family Physician found that over a period of 8 to 16 weeks, corticosteroid injections are more effective for managing frozen shoulder than oral corticosteroids, nonsteroidal anti-inflammatory drugs NSAIDs , and physical therapy. Cortisone shots are often used to treat knee or hip osteoarthritis. Carpal tunnel syndrome is compression of your median nerve that often causes tingling or pain in your hand.
A review of studies suggests that corticosteroids can lead to short-term relief in about 45 out of people. Trigger finger is the locking of a finger caused by inflammation of the tendons. The study mentioned earlier found 54 to 86 percent cure rates after corticosteroid injections. Bursitis is inflammation of small fluid-filled sacs called bursae found around your joints. Cortisone injections may help reduce this inflammation temporarily. Corticosteroid injections for the bursa around the head of your femur provide greater pain relief at 6 weeks and 3 months than physical therapy and pain relievers, but not after one year.
According to a review of studies , the amount of cortisone that gets absorbed into your blood seems to vary significantly between people. But both joint and epidural injections can have effects that last for weeks. The most common side effects of steroid injections include:. Your insurance may cover some or all of the cost.
