Patients with an acute attack of anxiety disorder will experience panic, chest tightness, difficulty breathing, hand numbness, hand tremors, and in severe cases, feelings of near death, fainting, or fear of losing control of themselves. Because of this strong feeling of loss of control, near death or fainting, patients will repeatedly seek help from people around them or call 120 for repeated visits to the hospital, but on the way to the hospital or after arrival, the patient’s symptoms will slowly ease down, and the doctor will perform relevant tests on the patient and find no specific positive test results. Despite this, because of the extreme sense of loss of control, near-death or fainting often appear from time to time, patients often appear to worry about re-emergence in general, and even appear to rub their hands and feet, fidgeting, such a state actually causes great impact on patients’ study, work and life.
