Once mastitis develops, it is best to lie down or lie flat, and try not to lie on the side, because lying on the side is easy for the body weight to press on the affected side of the breast, which will easily lead to ischemia of the mammary gland and poor return, which may aggravate the symptoms of the breast, and make the mastitis appear more obvious redness, swelling and pain, and other inflammatory reactions. The actual breasts of the patients who are lying on the floor are usually not in a good condition, and the blood flow will help the inflammation to subside, which will help the recovery of the condition. The patients of the mastitis patients should try to hold up their breasts with their bras to prevent the breasts from prolapsing, which will lead to the aggravation of the symptoms, and at the same time, they should take the active anti-inflammatory and symptomatic supportive measures, and they can also apply the infrared microwave physiotherapy and the sensitive antibiotics to carry out the anti-inflammatory and symptomatic treatments when necessary.
