Bernheim's Disease
An ailment first discovered in Pennsylvania horses in the 1850s. It spread to humans in the 1860s, and developed into a 100 year curse.
Symptoms
Patients frequently first reported with stomach pain after coming into contact with a horse. Over the next few hours, it developed into a stomach full of blood that diffused through the skin in hideous boils, causing the flesh to melt off in a way doctors referred to as "Not Good." If a patient survived this first bout, their prognosis was usually good, and they would often be able to return to work in a week or less.
Treatment
Dr. Jens Brenner pioneered many experimental treatments.
