English to Spanish Art/Literary Religion 19th century book about Christian mothers

A little girl we will suppose cuts deeply her hand. Her mother is so kind that she will not let a physician be called, for fear he should hurt her daughter in probing and dressing the wound. Day after day this kind mother beholds the increasing and extending inflammation. She strives in her ignorance to assuage the agony of the wound, till, after many days of excruciating suffering, the physician is called to save her daughter's life by amputating the limb. When the accident first occurred, a few moments of attention and trifling pain would have prevented all these dreadful consequences.

"la agonía de la herida" no me suena muy bien.
