Suddenly, having menstruation for 15 days and lower back pain, what's going on?

Patient's question:

No

Doctor's answer:

Considering it might be menstrual irregularity, you can check your endocrine system and also have a color Doppler ultrasound to examine the uterine cavity. Actively treat the cause, and you can try taking Wuji Baifeng Wan and Xiaoyao Wan. Appropriately supplement estrogen and eat more soy products. Wishing you good health.
