What is the reason for yellow leukorrhea and lower back pain?

Patient's question:

Last winter's treatment and effectiveness: None
What kind of Western medicine can be effective: Eat something

Doctor's answer:

Leukorrhea appears foamy, abundant, accompanied by itching of the external genitalia and vagina. If a vaginal leukorrhea smear test is performed, motile trichomonads can be observed. This is due to infection with trichomonads caused by unclean water in baths, tub baths, or sitz baths. This condition often leads to purulent infection due to scratching caused by intense itching of the vaginal opening, resulting in leukorrhea turning into yellow, purulent, foamy discharge.
Purulent leukorrhea: Leukorrhea appears yellow or greenish, often accompanied by symptoms such as general weakness and low-grade fever. This may indicate acute vaginitis or cervicitis. Inflammation suggests bacterial infection, and medical attention should be sought promptly.
The recurrence of yellow leukorrhea poses a serious threat to women's health. Patients should pay attention to follow-up tests after menstruation, maintain a light diet, and avoid spicy or irritating foods.
