It is normal to have sore feet in the second month of pregnancy. Due to the continuous weight gain of pregnant women during pregnancy, the ankle joints and knee joints on both sides are subjected to greater stress, resulting in compensatory muscle strain and fatigue and soreness, which is the result of the formation of a large amount of lactic acid in the body that has not been eliminated. It is recommended to use as little medication as possible because the fetus is in an unstable state in the second month of pregnancy and too much medication will affect the fetal development. At the same time, if leg swelling occurs, you can put your feet up at night when you sleep, which is conducive to venous reflux and reduces the swelling and soreness of the feet, and will recover completely in about 5-7 days. If self-treatment does not relieve, hospital consultation is recommended.
