If lumbago occurs in late pregnancy, it needs to be treated according to the actual cause, as follows: 1. If the lumbago is caused by lumbar muscle strain, you can use local heat compresses to relieve it, such as hot water bags or hot towels to warm the lumbar area, which can play a certain role in relieving it; 2. The problem is that there is no good treatment for this condition, so pay attention to more bed rest and avoid prolonged standing and sitting. Women are prone to lumbar pain in late pregnancy because the fetus is gradually increasing in size. If the symptoms of low back pain are not obvious, no special treatment is needed and more rest is sufficient. Pregnant women in late pregnancy should be careful not to do strenuous exercise and should rest in bed more often.
