Girls with stinging urine should drink more water and take anti-inflammatory drugs. You can take erythromycin, 0.3g each time, orally once a day, or you can also take oral Chinese medicines, such as Sanjin tablets, Hot Lin Qing, urine retention tablets, etc. These Chinese medicines have anti-inflammatory and diuretic functions. It is recommended to have a routine urine test to confirm whether there is a urinary tract infection. Red blood cells and white blood cells are seen in the urine test, which is a manifestation of urinary tract infection. When the pain is severe, it is recommended that you can take sodium bicarbonate orally, 0.5g each time, twice a day, which can effectively alkalize the urine and relieve the symptoms of painful urination.
