Abstract
We report a case of post coronavirus disease 2019 (COVID-19) condition, in which the patient suffered from a severe sense of fatigue and brain fog that was successfully treated with Kampo therapy. The patient was a 21-year-old man. He had been diagnosed with COVID-19 and hospitalized for follow-up examinations. He recovered without any complications and was discharged from the hospital, but continued to suffer from a severe sense of fatigue, coldness, dizziness, and a loss of concentration. Because of these symptoms, he had to spend most of the day lying down. One month later, he was hospitalized to receive Kampo therapy. We administered bukuryoshigyakuto for 2 weeks referring to his severe coldness and fatigue and then changed to renjuin for his fluid disturbance and blood deficiency. After starting Kampo therapy, his fatigue and dizziness gradually improved. He was discharged after 3 weeks of hospitalization and received Kampo therapy as an outpatient. One month later, he reported a dull feeling in his stomach and depression. We switched to kamikihitogohangekobokuto and added hachimigan. His activities of daily living improved and he could take 4.5-kilometer walk. He could return to work 4 months later. Kampo therapy may be useful for post COVID-19 condition that causes a sense of fatigue and brain fog.
