Subacute thyroiditis is an uncommon diagnosis in primary care and may initially resemble upper respiratory infections. Its nonspecific symptoms—such as odynophagia, anterior neck pain, and constitutional manifestations—often lead to repeated consultations and ineffective treatments. This case illustrates the importance of clinical suspicion and the role of point-of-care ultrasound in evaluating persistent throat-related symptoms that do not align with typical ENT findings.A 51-year-old woman presented with a three-week history of persistent odynophagia, neck pressure, low-grade fever, malaise, and unintentional weight loss, despite multiple evaluations and antibiotic courses. A detailed history and focused cervical examination revealed tender bilateral lymphadenopathy and a painful thyroid mass mobile with swallowing. Point-of-care ultrasound was performed to assess for structural abnormalities, and laboratory tests were ordered, including thyroid hormones, CRP, ESR, and thyroid autoantibodies. Corticosteroid therapy was initiated with a gradual taper planned over six to eight weeks. Follow-up laboratory studies and a formal cervical ultrasound were scheduled to monitor disease progression and treatment response.This case presents an atypical clinical picture in which odynophagia predominated despite a normal oropharyngeal examination. It demonstrates how subacute thyroiditis can be overlooked when symptoms overlap with more common infectious conditions. The case also highlights the expanding diagnostic capability of primary care through bedside ultrasound, a tool increasingly accessible to frontline clinicians.This case underscores the need to consider thyroiditis in patients with persistent throat pain and anterior neck tenderness that do not respond to standard therapies. Point-of-care ultrasound is a valuable tool that enhances diagnostic accuracy and may reduce unnecessary treatments. Future applications include broader implementation of ultrasound training in primary care and the development of standardized diagnostic pathways for evaluating prolonged cervical discomfort.Laboratory findings confirmed subacute thyroiditis, with suppressed TSH, elevated T4, and markedly increased inflammatory markers. Rapid clinical improvement after corticosteroid initiation aligned with expected disease behavior. The case underscores how early recognition prevents delays and avoids unnecessary medications, while bedside ultrasound supports real-time clinical decision-making.Subacute thyroiditis, though uncommon, should be included in the differential diagnosis of persistent odynophagia. Strengthening ultrasound competencies in primary care may improve earlier detection and outcomes.
