After urinating, I feel a little pain. What disease caused it?

After urinating, I feel a little pain. This may be a slight inflammation of the urethra. Most of this situation is urinary tract infection. Urinary tract infection is mainly caused by Gram-negative bacteria infection. It is recommended to drink more water, urinate more, pay more attention to hygiene, and effectively prevent the incidence of infection. If there is pain in urination, drink more water temporarily, observe whether there is relief, and if there is relief, the disease has been effectively controlled. If the symptoms do not improve after drinking a lot of water, oral antibiotics are needed. Antibiotics suggest levofloxacin 0.2 g each time, 2 times a day orally, usually 3-5 days, you can completely control the disease.
