But later the vomited matter is blackened by blood which has escaped into the stomach from the ulcerated growth.
The infected tissue develops an ulcerated area, and a diphtheria membrane may form over the wound but is not always present.
Symptoms include painful, bright red, often ulcerated tonsils, enlargement of lymph nodes (glands) beneath the jaw, fever, and general discomfort.
Again, a fractured bone in a paralysed limb often fails to unite, while another in the opposite sound limb unites readily, and an ulcerated surface on a paralysed limb shows little healing reaction.
Where the surface is ulcerated it may be protected from external violence and placed under favourable conditions for healing by covering it with lint moistened with water and with oil-silk over it to prevent evaporation.
