Cortisone shots are injections that can help relieve pain and inflammation in a specific area of your body. They're most commonly injected into joints, such as your ankle, elbow, hip, knee, shoulder, spine or wrist.
Even the small joints in your hands or feet might benefit from cortisone shots.
Risks
Cartilage damage
Death of nearby bone
Joint infection

Temporary flare of pain and inflammation in the joint
Temporary increase in blood sugar

In general, you shouldn't get cortisone injections more often than every six weeks and usually not more than three or four times a year.
After the cortisone shot
Protect the injection area for a day or two. For instance, if you received a cortisone shot in your shoulder, avoid heavy lifting. If you received a cortisone shot in your knee, stay off your feet when you can.
Apply ice to the injection site as needed to relieve pain. Don't use heating pads.
Not use a bathtub, hot tub or whirlpool for two days. It's OK to shower.
Watch for signs of infection, including increasing pain, redness and swelling that last more than 48 hours.
