What causes back pain during pregnancy?

Many women often feel back pain after pregnancy. This is a symptom that occurs in many women. In fact, it is mainly because as the fetus continues to grow, the waist needs greater support to support the belly, so pain will occur in the joints and the waist and abdomen.

1. Most shoulder joint pain is rotator cuff tendinitis caused by overuse of muscles, which is common in pregnant women who lift heavy objects or often do shoulder lifting movements. Patients usually complain of shoulder pain and weakness at a specific angle (between 70° and 120°).

2. Lower back pain caused by excessive burden and lack of oxygen intensifies as the mother's belly grows, and becomes more obvious in the late pregnancy (mostly occurs after 5 months of pregnancy). The main symptoms of pain are inability to stand for a long time or soreness caused by maintaining the same posture for too long. However, this pain is concentrated in the waist and does not extend to the lower limbs.

3. Insufficient support: The pain in the sacroiliac joint caused by insufficient support will be more severe than the lower back pain, and it will become more severe towards the end of pregnancy. This pain occurs on both sides of the buttocks (below the lumbar spine) and extends to the front of the thigh. Some women continue to have severe pain for several months after giving birth.

4. A small number of intervertebral disc ruptures. A very small number of pregnant women may have intervertebral disc (the cartilage of each vertebra) rupture and compression of the sciatic nerve. The main symptoms are numbness and weakness in the thighs, and even difficulty in urination and defecation, which is quite inconvenient. Of course, this situation is not necessarily related to pregnancy, but since medical treatment during pregnancy must be particularly cautious, medical treatment is necessary. Do not gain too much weight during pregnancy. There is no specific target group for low back pain during pregnancy. If the expectant mother has a history of low back pain before pregnancy, the proportion of low back pain during pregnancy is higher.
