Redness at the girl’s urine and also pain means that the girl has an inflammation in the urethra. This condition suggests that the patient must usually wash the perineum with water and keep it dry because there are a lot of bacteria attached to the perineum of women and the urethra is very close to the vagina, which can easily lead to retrograde infection of the urethra. In this case, you should also have a routine urine test to see if the surrounding inflammation is serious and if there are white blood cells in the urine. If there are more white blood cells, you should take oral broad-spectrum antimicrobials, the most common being cephalosporins, represented by cefdinir, 0.1g each time, 3 times a day orally, and drink more than 1500ml of water a day. by taking oral anti-inflammatory drugs and washing locally, the symptoms will soon be relieved.
