The presence of sore nipples during ovulation is caused by the stimulation of the estrogen peak in the body. This can be done by local massage, but try not to stimulate the nipples as this may cause more painful performance. Wear loose underwear, do not wear tight underwear, compression can also cause persistent nipple pain. You can also apply warm water at about 45°C to relieve nipple pain, but be careful not to apply too much force or too high a temperature to avoid rupture or aggravation of the milk ducts and painful performance. The nipple pain will end in 3-5 days and will not affect your health, but if it persists, it is recommended to go to the hospital to register for an ultrasound examination of the mammary gland, and according to the situation, medication and relief.
