In July 2022, a 38-year-old male presented to a clinic at the King Fahd Medical Research Centre, Jeddah, Saudi Arabia with a subcutaneous fibrous cord extending from the axilla to his left arm. He complained of painful abduction of his left shoulder and pain in the left shoulder extending from the axilla to the medial aspect of the arm. He reported that the cord appeared 2 weeks prior to his attendance at the clinic and 2 days after repetitive physical activity using a jumping rope. He also reported that the cord was longer and more prominent once it appeared. The patient had no history of chronic illnesses. The patient had a family history of hypertension and type 2 diabetes mellitus. He was not on any medication, except esomeprazole, for gastric acidity and heartburn. On physical examination, he was apparently healthy with a body mass index (BMI) of 33.1 kg/m2. Inspection showed a 12 cm subcutaneous band or cord running from the left axilla to the medial side of the left arm (Figure 1). The cord was fibrous and thin upon palpation. The patient was then diagnosed with AWS. The patient was advised to undergo self-massaging. The cord and its accompanying pain symptoms gradually resolved over 8 weeks without any need for analgesics (Figure 2). The reporting of this study conforms to CARE guidelines. Written informed consent for publishing clinical data and images relevant to this case report was obtained from the patient.
