Patients with UTI may experience urinary tract irritation in the form of painful urination, especially during urination, with significant stinging and itching in the urethra. And if the UTI is complicated by an episodic infection with cystitis, there will also be significant cramping pain in the lower abdomen in the posterior segment of urination, which is bladder contraction resulting in bladder contracture pain. The UTI, even if there is obvious painful urination, difficult urination, abdominal pain and other symptoms, must drink more water, more urination, not because of the pain and not to drink and urinate, which is not conducive to the healing of the infection. Only by allowing urine to constantly flush the urethra and bladder can the pathogens on the urethral mucosa be taken away more quickly, and only then can the infection be promoted to heal as soon as possible. Patients with UTIs can take medications such as flavonoid permethrin tablets to help improve urinary tract irritation symptoms such as frequent, urgent and painful urination.
