In ancient Greek or Roman times, the patient of Buerger's Disease was probably treated same as leprous patients and taken to remote places (caves).
In modern times, one of American doctors, Buergers died from unknown disease, which made his arms and legs decayed. But till the last moment he died, no one could find the cause of the disease. The academic world named the disease as "Buerger's Disease".
Nowadays, most people call it as 'obstruction of blood vessels', 'osteomyelitis' or 'necrosis of arms and legs'. Buerger's Disease is declared as incurable disease of modern medical science. Owing to this fatal disease, hundreds and thousands of patients suffer and get victimized to the disabled.

What are ulcerative foot and Buerger's disease?
 It is the disease that causes inflammations on peripheralartery and vein. It is very often detected among Asians, especially to young male and men in the prime of manhood. Once you get inflammations on artery and vein on your arms and legs and then have thrombi, blood cannot circulate normally because thrombi block the inside of the vessels so that peripheral tissues get necrosis or arms and legs(feet) get cold and turn into purple or black. While these symptoms are developing, there is severe pain on arms and legs(feet), and that generates ulcer. If any treatment does not effectively work very well, arms and legs have to be removed.
