Anxiety and anxiety-related disorders include generalized anxiety disorder, panic disorder, conversion disorder, hypochondriasis, somatoform disorder, somatization disorder, somatoform pain disorder, etc. (see “Classification and Diagnostic Criteria for Somatoform Disorders”). There are two other disorders, neurasthenia and depressive neurosis, which are rarely diagnosed by psychiatrists anymore according to modern diagnostic criteria, and most of these two disorders can be classified as anxiety disorders. These anxiety and anxiety-related disorders can mimic the symptoms of many kinds of somatic disorders, affecting almost any part of the body and any organ, from head to toe. Of course, symptoms can appear in different parts of the body for different patients; the same patient can present with different symptoms at different times. Some patients have only one somatic symptom, and some patients can have many symptoms at the same time. Sometimes, I would ask them, “Is there any part of your body that is not sick?” Some patients will answer me like this, “There is no piece that is well.” Some anxiety manifests itself in the head, such as headache, dizziness, tight scalp, ringing in the ears, tinnitus, insomnia, eye pain, nasal congestion, twitching at the corners of the mouth, and twitching in the limbs, etc. Many patients have had multiple CT or MRI examinations of the head as a result, and have also had surgery by mistake as a result, commonly such as nasal septal surgery. Some anxiety manifests in the neck or shoulders, see “Cervical spondylosis and anxiety disorders” and “Foreign body sensation in the throat” above. Some anxiety manifests itself in the heart and lungs and is often treated as heart or lung disease for several years. I have also seen patients who have been misdiagnosed and mistreated for decades. Those who have been misdiagnosed and mistreated for years or decades are quite common in general hospitals. Some of the anxiety manifests itself in the gastrointestinal region, and some patients have undergone a major gastrectomy as a result, and after the cut, their symptoms persist and they end up coming to us for consultation and treatment. In one case, the patient was diagnosed with ulcerative colitis in the local hospital, and was also treated in several large hospitals in Guangzhou, and there were really a few small ulcers on colonoscopy, that is, the treatment was ineffective, many fruits and foods could not be eaten, and once eaten, abdominal pain and diarrhea. It took a few years to come to me for anxiety treatment, and now I can eat everything. It is much more common to see this in the genitourinary system, see: “The long untreated prostatitis turned out to be a hypochondriac”. There are also anxiety manifested in the extremities. One woman had lumbar spine surgery for back and leg pain and foot weakness, and before the surgery, the doctor said she would definitely be able to walk after the surgery, but she still couldn’t walk after the surgery. She later received anti-anxiety treatment from me and is now helping her daughter with her children abroad. There are also anxiety manifested on the surface of the body, such as itchy skin; the prevalence of anxiety and anxiety-related disorders is also quite high in cases requesting surgical cosmetic surgery. The cupboard is a place where you can find the mackerel, the mackerel, the mackerel, the mackerel and the mackerel. When anxiety is transformed into somatic symptoms, sometimes the emotional aspect of anxiety may not be obvious instead, and a small number of patients do not even have anxiety. Therefore, when other physicians suspect that such patients have a psychological problem and suggest that they see a psychiatry or psychology department, a significant number of patients are reluctant to do so. Of course, there are other reasons why patients with this type of anxiety or anxiety-related disorders are reluctant to see a psychiatrist or psychologist, such as personality factors, narrative disorders, etc. More importantly, there are subconscious mechanisms, which are not discussed in detail here, see “What is the subconscious?”. .
