Pain in the right thigh root during pregnancy is considered to be related to the fetal position of the fetus. Because after pregnancy, the fetus may compress the nerves when sitting on the fetus, which will easily lead to pain at the root of the thigh. In this case, usually try to take a rest in the left side position, which can relieve the pain caused by the compression of blood circulation, resulting in poor circulation. Because after pregnancy, most of the time the uterus is in a right-handed position, resting in the left side can reduce the local pressure of the right-handed uterus and also reduce the strain on the left ligament. If you have calcium deficiency during pregnancy, it will also cause leg pain, you should take calcium supplements in time, take calcium tablets for pregnant women or eat foods with high calcium content to relieve the pain caused by calcium deficiency.
