Nerve sensitivity may hold key to why some shoulder pain treatments fail

This study aimed to understand if a condition called 'central sensitization'—where the nervous system becomes overly sensitive to pain—affects how well steroid injections work for chronic shoulder pain. Researchers followed 44 adults with rotator cuff pain who received a standard steroid injection. They compared results between patients who had this nerve sensitivity before treatment and those who did not, checking pain and function over three months.
