Introduction
Whether lower back pain during the second trimester of pregnancy is normal depends on its cause. It is considered normal when caused by the enlarging uterus exerting pressure on the lower back and surrounding tissues, or by elevated hormone levels during pregnancy that lead to ligament laxity in the back. However, back pain can also result from muscle strain due to fatigue, exposure to cold and drafts, increased spinal load during pregnancy, or the development or worsening of lumbar disc herniation.

Generally speaking, whether severe lower back pain during the second trimester of pregnancy is normal depends on the specific underlying cause. The detailed analysis is as follows:

1. Normal

As pregnancy progresses, the growing uterus gradually enlarges and shifts the body's center of gravity, causing significant pressure on the lower back and surrounding tissues. Additionally, elevated hormone levels during pregnancy can lead to relaxation of ligaments in the back. Both of these are normal physiological changes and do not require special treatment.

2. Abnormal

Excessive fatigue during pregnancy, exposure of the waist to cold or drafts, or maintaining the same posture for prolonged periods may lead to strain of the lower back muscles. Pre-existing conditions such as lumbar disc herniation may also worsen due to increased spinal load during pregnancy, triggering or exacerbating symptoms. These situations are considered abnormal, and it is advisable to seek timely medical evaluation and treatment at a hospital.

During pregnancy, it is important to keep the body warm, maintain proper posture, get adequate rest, and avoid overexertion. If necessary, gentle massage of the lower back performed by a qualified healthcare professional may help relieve symptoms.
