[Introduction]
Acute mastadenitis refers to infection of the breast due to invasion of bacteria into mammary glands and lac-tiferous ducts. This problem is frequently encountered among women with breastfeeding, especially primipara. It usually occurs 3 - 4 weeks after labor due to rupture of nipple and invasion of bacteria complicated by unsmooth secretion of milk and stagnation of milk. The clinical ma-nifestations are local swelling, pain, tenderness and hard nodules of the breast, accompanied by aversion to cold, fever nnd enlargement of lymph nodes over the armpit on the affected side. This disease pertains to breast abscess in TCM due to invasion of pathogenic factors or accumula-tion of milk; or due to mental upsets and stagnation of liver qi; or due to excessive intake of rich foods and accu-mulation of heat in the stomach meridian that lead to the obstruction of the vessels and stagnation of qi, blood and milk.
The clinical manifestations are sudden lumbago and limited movement of the waist. TCM holds that lumbago is caused by improper exertion or falling and contusion that lead to impairment of the lumbar tendons and meridians as well as stagnation of qi and blood.
