Shock waves may ease arm pain after breast cancer surgery

This study tested a treatment called extracorporeal shock wave therapy (ESWT) for people with axillary web syndrome, a common complication after breast cancer surgery that causes pain and limited arm movement. Twenty patients who had breast cancer surgery and developed this condition received low-energy shock waves to see if it improved their shoulder range of motion and reduced pain. The goal was to find a non-invasive way to help patients move better and feel less discomfort.
