Fever from milk blockage is caused by acute mastitis, which is usually caused by localized bacterial infection and is not contagious to others.
When you are not in the right position to breastfeed, use a milking machine, crack your nipples due to breastfeeding, or have a buildup of breast milk, bacteria may enter the breast, leading to acute mastitis, redness, swelling, and heat pain in the breast, as well as the breastfeeding woman’s own immune system decreases, and the emotional fluctuation is also the reason for the formation of acute mastitis.
The actual fact is that it’s not a contagious disease, it’s not contagious to other people, and it’s possible to recover from the disease by unblocking the milk ducts and combining them with anti-infective treatments such as penicillin, benzathine, or the first generation of cephalosporins such as cephradine.
