Also yīn sores. A sore on the back, sacrum, heels etc., that develops in comatose, paralyzed, or weak patients confined to bed. Bedsores start as red patches which gradually develop into ulcerations that are difficult to heal. They are attributable to major depletion of qì and blood in enduring illness with confinement to bed that causes friction and prevents the normal movement of qì and blood, thus depriving the skin of nourishment.
