Foshan Fifth People’s Hospital Rehabilitation Department Feng Yunhua: According to the medical history and information you provided, it is difficult to diagnose your disease immediately. But one thing is that if everything is normal in your examination, there will be no major disease. May I ask what kind of work you are engaged in can be stressful? It is recommended to consult a psychological specialist, or bring relevant medical records to the clinic.
