What are joint injections?
Joint injections are shots into a joint, such as the knee or shoulder. They are used to put in medicines, such as pain relievers and steroid medicines. Steroids can help reduce inflammation. A steroid shot can sometimes help with short-term pain relief when other treatments haven't worked.
How are joint injections done?
First, the area over the joint will be cleaned. Your doctor may then use a tiny needle to numb the skin in the area where you will get the joint injection.
If a tiny needle is used to numb the area, your doctor will use another needle to inject the medicine. Your doctor may use a pain reliever, a steroid, or both. You may feel some pressure or discomfort.
Your doctor may put ice on the area before you go home.
Joint injections: When to call
Call your doctor now or seek immediate medical care if:
- You have signs of infection, such as:
- Increased pain, swelling, warmth, or redness.
- Red streaks leading from the site.
- Pus draining from the site.
- A fever.
Watch closely for changes in your health, and be sure to contact your doctor if you have any problems.
How can you care for yourself at home after a joint injection?
- Put ice or a cold pack on the area for 10 to 20 minutes at a time. Put a thin cloth between the ice and your skin.
- Ask your doctor if you can take an over-the-counter pain medicine, such as acetaminophen (Tylenol), ibuprofen (Advil, Motrin), or naproxen (Aleve). Be safe with medicines. Read and follow all instructions on the label.
- Avoid strenuous activities for several days. In particular, avoid ones that put stress on the area where you got the shot.
- If you have dressings over the area, keep them clean and dry. You may remove them when your doctor tells you to.
