Patients often have symptoms of itching during urethral infection, and the most important cause is itching caused by the irritation of inflammatory factors in the urethra. When a urethral infection occurs, the urethral epithelium can be highly congested and edematous, with a surface of erosion or ulceration, and superficial sensory nerves are exposed, which can make the urethral epithelium become abnormally sensitive, and the inflammatory stimulation is more likely to produce itchiness. In addition to the symptoms of itching, urethral infections can also manifest as symptoms of frequent urination, urinary urgency, and painful urination. If a urinary tract infection occurs, patients are advised to undergo routine urine tests and to treat accordingly according to the different causative factors. If the infection is bacterial, treatment with quinolone antibiotics, such as levofloxacin, is recommended. In case of mycoplasma and chlamydia infections, macrolide antibiotics are recommended and azithromycin is commonly used clinically for treatment. In addition to the above treatment, patients are advised to pay attention to personal hygiene and often wash their urethra with warm water to keep it dry and clean. Choose cotton underwear, preferably washed and exposed to sunlight to kill the poison. Pay attention to a light diet, eat more fresh fruits and vegetables, and avoid spicy and stimulating foods. Drink more water and urinate more often, the flushing of urine can reduce the bacteria in the urethra. In addition, pay attention to rest after the appearance of urinary tract infection, and if you perform strenuous activities, it may aggravate the symptoms.
