During this period of discomfort, a physical examination revealed elevated white blood cell count. The primary concern is likely bacterial infection or a hematologic disorder; however, in some patients, it may be associated with impaired immune function. If bacterial infection is confirmed, antibiotic therapy may be initiated under the guidance of a physician. Additionally, maintaining regular and healthy sleep habits is recommended.
