The increase in oestrogen and lactogen secreted by the placenta after pregnancy leads to a decrease in the elasticity of tendons and muscles, a decrease in the tension of the ligaments near the finger joints and joint laxity, resulting in pain in the finger joints, which can be relieved when hormone levels return to normal after birth. In late pregnancy, the pregnant woman’s whole body is heavily loaded with volume, which can lead to localised oedema in the finger joints and cause finger joint pain.
