Droopy Shoulder Syndrome: A Gateway to Thoracic Outlet Syndrome.

Droopy shoulder syndrome (DSS) manifests as discomfort or abnormal sensations in the neck, shoulder, chest, and upper limbs, resulting from tension on the brachial plexus caused by abnormally low shoulder positioning. This case report examines the presentation and management of a patient with DSS, a rare but crucial precursor to thoracic outlet syndrome (TOS). The patient, a 22-year-old male, presented with progressive pain and tingling in his left upper limb, shoulder, chest, and neck. Comprehensive examination and imaging studies led to a diagnosis of DSS. Physical therapy prevented progression to full-blown TOS, highlighting the importance of early recognition and intervention. This case underscores the diagnostic challenges and therapeutic strategies essential for managing this syndrome, preventing complications, and restoring patient function.
