Effects of cortisone shots

Cortisone shots are commonly used to reduce pain and inflammation, but they come with a range of potential short-term and long-term side effects. Most effects are mild and temporary, but repeated or high-dose shots can have more serious consequences.[1][2][3]

Common Short-Term Effects

  • Temporary flare-up of pain, swelling, and irritation in the area of injection, typically lasting up to two days.[3][4][1]
  • Skin lightening or discoloration at the injection site, especially in those with darker skin.[4][3]
  • Facial flushing, which generally resolves within a day or two.[3][4]
  • Elevated blood sugar, especially a concern for people with diabetes.[5][4][3]
  • Bruising or redness around the injection site.[4]
  • Short-term insomnia or higher-than-normal appetite in some cases.[3][4]

Less Common or Rare Side Effects

  • Infection at the injection site (septic arthritis), which is a medical emergency.[4][3]
  • Nerve damage, which may lead to pain, numbness, or weakness.[1][4]
  • Allergic reactions, such as hives or swelling.[3]

Long-Term Risks and Complications

  • Cartilage damage and accelerated loss within the joint, particularly with repeated shots.[5][1][4][3]
  • Tendon weakening or rupture, especially if injected near or into a tendon.[1][5][4]
  • Thinning of nearby bone (osteoporosis) and soft tissue, as well as fat atrophy or skin dimpling at the injection site.[5][1][4]
  • Rare but severe complications include avascular necrosis (death of nearby bone tissue) and adrenal insufficiency.[4]
  • Higher risk or faster progression of osteoarthritis in some cases.[6]

Clinical Practice and Recommendations

  • Most medical providers limit cortisone shot frequency to reduce risk of cartilage and bone damage.[1][5][3]
  • Individuals on blood thinners or with an active infection are generally advised not to receive cortisone shots.[2][4]
  • Patients should monitor for serious symptoms like fever, severe joint pain, or intense swelling after the shot and contact their healthcare provider if these occur.[4]

Cortisone shots provide significant but usually temporary pain relief and are considered safe when used appropriately, but overuse or use in certain individuals can result in serious adverse outcomes.[2][1][3][4]
