Once deficient, it is easy to cause lumbago and lumbar pain. When lumbago is accompanied by leg cramps and sciatica, in addition to quickly supplementing vitamin B12 and calcium, it is also necessary to consult a doctor in time to seek help. Lack of minor people, it is recommended to dietary supplements. And in the later stages of pregnancy, some pregnant women have contractions that manifest as regular back pain. It can also lead to the appearance of symptoms such as back pain and lumbago. Therefore, in the later stages of pregnancy, if there is severe back pain and abdominal pain, it may also be a symptom of labor. If the pain is unbearable, it is recommended to go to the hospital in time for examination.
