Can periarthritis of the shoulder be treated with corticosteroid injections?

　　A “block injection” (also known as a “local anesthetic and corticosteroid injection”) involves injecting a solution of specific concentration and volume directly into the affected area—for example, patients with tendon pain may receive block injections for treatment. Pain typically subsides following such an injection. Generally, 3–4 treatment sessions are recommended, and the procedure itself is minimally painful. Once administered, the medication rapidly alleviates pain. So, can adhesive capsulitis (frozen shoulder) be treated with block injections?

　　Can adhesive capsulitis be treated with block injections?

　　Yes, block injections are commonly used to treat adhesive capsulitis. The benefits generally outweigh the risks, as adhesive capsulitis primarily affects the tissues surrounding the shoulder joint and is often accompanied by localized tenderness. Such tender points usually do not respond significantly to topical treatments like medicated plasters or patches; however, early functional exercise remains essential in managing adhesive capsulitis. Therefore, when distinct localized tender points are present, targeted local block injections may be appropriate. These injections provide effective analgesia and help preserve a certain range of motion in the shoulder joint—thus facilitating more effective functional rehabilitation.

　　After receiving a block injection for adhesive capsulitis, patients must restrict shoulder joint movement to prevent exacerbation of periaricular pain. Additionally, spicy and stimulating foods, smoking, and alcohol consumption should be avoided post-injection to prevent disease aggravation due to irritation or infection at the injection site—which could manifest as redness, swelling, and pain.

　　In daily life, maintain a regular, balanced diet—avoid spicy and irritating foods, overeating, and staying up late. We hope this information proves helpful.
