In the early stage of pregnancy, due to the early pregnancy reaction, the body is more prone to fatigue and weakness, and therefore prefers to rest in bed, due to a small amount of food and less walking, the peripheral blood circulation of the whole body may be poorer, so the phenomenon of sore feet will occur. If the symptoms of sore feet are relieved by resting, massaging the feet and increasing the diet, the patient can be observed for the time being. If the symptoms of sore feet cannot be relieved after observation and swelling occurs, it is best to go to the hospital for blood tests such as HCG, urine routine and gynecological ultrasound. If the fetus develops well under the ultrasound and there is no abnormality, then we should see if there is poor peripheral blood circulation or a lack of minerals and vitamins, such as calcium, so as to take appropriate methods of symptomatic treatment in order to avoid affecting the health of the pregnant woman and the growth and development of the fetus. The health of the pregnant woman and the growth and development of the fetus will not be affected.
