Corticosteroid injections for shoulder periarthritis do have potential side effects, mainly including the following: 1. **Risk of infection**: Any injection carries a risk of infection. Although corticosteroid injections are typically performed under sterile conditions, there is still a possibility of introducing bacteria or other pathogens, leading to infection. 2. **Bleeding and hematoma**: Blood vessels may be damaged during the injection, resulting in bleeding or hematoma formation. 3. **Nerve injury**: If the needle inadvertently punctures surrounding nerve tissues, it may cause pain, numbness, or other neurological impairments. 4. **Allergic reaction**: Some individuals may experience allergic reactions to the injected medication, such as redness, itching, or swelling of the skin. 5. **Other complications**: Long-term or frequent corticosteroid injections may lead to local soft tissue necrosis, muscle atrophy, ligament adhesion, and osteoporosis. Corticosteroid injections for shoulder periarthritis should be performed under the guidance of a physician. Post-injection care and observation are also important to prevent or minimize potential side effects.
