The main first symptom of Parkinson’s disease is hand tremors and tremors. You have seen on the Internet, in the Barcelona Olympic Games, boxing champion Ali with trembling hands to hold the torch to do the lighting of the action. In my clinic, many people recall that in the earliest stages, for example, when riding a bicycle, one leg could go up but the other couldn’t, or someone else noticed that he always walked with a dragging sound. The sound was always a dragging sound. Therefore, Parkinson’s disease is a relatively insidious disease and has many symptoms, which are not the same for everyone. The onset of Parkinson’s disease is relatively insidious in many patients, and some patients are diagnosed with Parkinson’s disease only after 10 years or more. This is because some of the early symptoms of Parkinson’s disease are easily ignored, such as constipation, loss of smell, abnormal walking posture, stiffness of the limbs, etc. Some patients do not pay attention to these symptoms, or go to other departments, such as orthopedics, for consultation, and after taking a film, everything is normal, so they do not care. Therefore, for middle-aged and elderly people, if they have constipation, loss of smell, abnormal walking posture, or stiffness of the limbs, we need to consider Parkinson’s disease as an object of consideration. If some of the early symptoms of Parkinson’s disease appear and have been seen in other clinics, and all related diseases have been ruled out, such as leg pain and back pain, which are not orthopedic problems or problems in other departments, then you should go to a neurology or neurosurgery Parkinson’s disease specialist clinic and have a professional doctor look at it.
