The feeling of insect bite in the urethra or insect crawl in the vagina is manifested as psychological abnormalities and behavioral abnormalities. What are the diagnostic methods of this disease: Urethral tingling: A slight burning sensation and tingling in the urethra during urination are common symptoms of urethritis. Urethritis is a common disease, mostly seen in women, clinically divided into acute and chronic, non-specific urethritis and gonorrheal urethritis, the latter two with similar clinical manifestations, which must be differentiated on the basis of medical history and bacteriological examination. Insect bite sensation in the urethra or insect crawling sensation in the vagina: 1. History and symptoms without the manifestation of a specific STD. 2, There are abnormal psychological and behavioral manifestations with certain quality and personality defects. 3.Psychological and behavioral abnormalities affect normal work and life. The duration of the disease is more than three months. 4, physical examination and laboratory tests, no positive changes of STDs. Psychological abnormality Half-knowledge of the transmission route of STD, one-sided exaggeration of the possibility of non-coital contact transmission, high fear of STD, suspicion of having contracted STD, despite no history of sexual contact, and no suspicious symptoms, positive signs and laboratory basis of STD, but the fear cannot be restrained and repeatedly request for confirmation. Or those who had a history of pre-marital or extramarital sexual intercourse or suffered from STD, although STD has been ruled out or cured by physical examination and laboratory examination, they still have unresolved doubts and suspect that the doctor’s medical skills are low or the laboratory equipment is poor and the test results are wrong, so they keep changing doctors and hospitals to request for further examination and treatment. The attention to the things related to STD is increased, which is shown by the special attention to the outside words, books and magazines, sound and image related to STD, and the special sensitivity to the slight change and discomfort of oneself and even the normal physiological phenomenon. And think it is the symptom or early manifestation of STD. The patient’s medical history is very complicated, and he or she repeatedly emphasizes that the symptoms are related to STD, but they are unrelated, and often exaggerates the symptoms. Behavioral abnormalities Mainly high vigilance and avoidance of possible ways of infectious diseases. For example, they are afraid to share a room with their spouse, and use all daily necessities separately from others. Repeated forced washing, some seeking medical advice multiple times a day to relieve their great mental stress. Patients show unreasonable concern for the appearance and sensation of urethral, anal or vaginal secretions and genitalia. This may result in compulsive ideas or compulsive examination of the genitalia, which can itself cause irritation and discharge. The recognition of these symptoms (or the patient’s description of them) without objective evidence of infection or recurrence may contribute to STD neurosis and exacerbate the patient’s neurotic tendencies. Manual manipulation of the penis to produce discharge (often violent squeezing of the penile head and body rather than the usual careful manipulation) is characteristic of this group of patients. In addition, the patient may be paradoxically concerned with pigmentation irregularities and skin surfaces, dermatomes, sebaceous cysts, and hair follicles. A strong demand for treatment when neither infection nor lesion is confirmed is also a sign of venereal neurosis. Signs The main signs are autonomic dysfunction, such as flushing and heat on the face, palms and plants, excessive sweating, panic, rapid heart rate, cardiac arrhythmia, and trembling of both hands. However, there are no positive signs of venereal disease in external genitalia and systemic examination. The above-mentioned clinical manifestations disappear or are not obvious during work stress, attention diversion, and sleep. Laboratory tests There are no abnormal findings in any laboratory tests related to STDs.
