If you get frozen shoulder during the menstrual period, you must adjust your lifestyle and keep your shoulder warm to avoid getting cold. Adjust your breastfeeding posture. Many mothers get frozen shoulder due to improper breastfeeding posture, so keep your shoulders relaxed while breastfeeding, adjust to lying down breastfeeding, avoid sitting down breastfeeding, and pay attention to holding your child for a long time. You can use medication to relieve the symptoms of frozen shoulder, such as applying plasters around the shoulder and using infrared baking lamps to relieve the discomfort of frozen shoulder. If the condition is severe, surgery may be necessary.
