Is it harmful to the body to receive cortisone injections for shoulder periarthritis?

There are indeed certain potential risks associated with corticosteroid injections for shoulder periarthritis: 1. Local soft tissue infection: Improper technique or reduced immunity in the patient may lead to local soft tissue infection, and in severe cases, purulent arthritis. 2. Capsular injury: Injection therapy may damage the ligaments and joint capsule around the shoulder joint, which could easily result in strain injuries during movement. 3. Osteoporosis: Long-term or repeated injections may cause osteoporosis, increasing the risk of fractures. 4. Muscle atrophy: Prolonged and frequent use of injection therapy may lead to local muscle atrophy, affecting muscle function and mobility. 5. Local bruising: Capillaries may be damaged during the injection, resulting in localized bruising and swelling. Patients with shoulder periarthritis should be fully aware of these potential risks before undergoing injection therapy and should receive treatment under the guidance of a physician.
