Following the COVID-19 pandemic in 2020, encounters with patients experiencing post-vaccination pain have become increasingly common in outpatient settings. This case report highlights a 47-year-old male, initially devoid of any underlying conditions, presenting with persistent lower back and bilateral thigh pain following his third COVID-19 vaccination. Despite analgesics, his pain intensified, prompting further investigation. Lumbar MRI revealed mild disc protrusion at L4-L5 and widespread signal intensity abnormalities in the vertebrae and pelvis, suggesting a hematogenous disorder. Subsequent blood tests showed decreased platelets and atypical leukocytes, leading to a final diagnosis of acute myeloblastic leukemia after being transferred to the department of hematology. This case underscores the importance of comprehensive assessment in patients with post-vaccination symptoms, where seemingly routine pain may indicate underlying severe conditions. It highlights the necessity for pain physicians to consider a broad differential diagnosis, including serious hematological diseases, when evaluating post-vaccination complaints.
