About 3 days before menstruation, severe back pain and cold back appeared. There were a lot of blood clots when I came. What's the disease? How is it caused?

This is a symptom of gynecological cold. There are a lot of blood clots, which means that your menstruation was not clean last month because the uterus caught cold, and this time it was washed down by new menstrual blood. Low back pain and cold back indicate that the symptoms of a cold are very serious. Rome was not built in a day. You haven't paid attention to keeping warm during your period for a long time, have you?

Put on more clothes, keep your waist and abdomen warm, and soak your feet with hot water bag or hot salt bag to relieve symptoms.

Cold uterus will make gynecological organs lack motivation, reduce immunity, and easily lead to various gynecological inflammation. If the menstrual blood is discharged with insufficient power and temperature, it is easy to form blood clots. If the blood clot is not discharged cleanly, bacteria will breed after a long time and may accumulate. Mother mussels will become pearls because of a grain of sand, and when the blood clot is big, they will become uterine fibroids. As for frequent urination, it may be abdominal oppression caused by poor qi and blood, which is not a big problem, but if you don't pay attention to keeping warm, it will turn a small problem into a big problem.
