This work reports the case of a middle cerebral artery infarction patient with hyperhidrosis and left upper extremity paresthesia whose condition improved following Korean medicine treatment. The patient was hospitalized for 10 days and treated with herbal medicine, mainly <i>Hwanggigyeji-tang</i>, and acupuncture, electroacupuncture, and moxibustion. The hyperhidrosis was clinically classified and the patient’s subjective discomfort in this regard was also checked. A subjective percentage of strength and sensation in the left extremity was evaluated to assess the clinical effects of the treatment. After treatment, the hyperhidrosis classification improved from Grade 3 to Grade 0, and the patient’s subjective discomfort was greatly improved and continued for the two weeks after discharge. In addition, subjective strength and sensation improved by 20% and 5%, respectively, compared to time of admission. These results suggest that Korean medicine is effective in treating paresthesia after stroke and long-lasting hyperhidrosis.
