Lower back pain is common from the second trimester as the growing uterus shifts your centre of gravity. Strengthening the core and glutes reduces it significantly. A support pillow between the knees while sleeping relieves pressure on the hips and lower back. Heartburn typically worsens as the uterus pushes against the stomach.
Swollen ankles are caused by increased blood volume and uterine pressure on veins. Elevating the feet during rest and regular walking help. Sudden severe swelling in the face or hands can be a sign of pre-eclampsia and requires immediate medical attention.
