What is the backache before your period?

Before the next period, the back pain is mainly caused by the imbalance of hormone secretion in the body. Before the period, the estrogen level in the female body increases, which will cause various discomfort. At this time, the reproductive system begins to be congested, and lumbosacral pain will occur. Under normal circumstances, no treatment is needed. After the menstruation, the brake will be relieved.
