Hello,
Ulcers develop on the back like triangular shape, start as pear-shaped or butterfly shaped and color may vary from black, purple, blue. Unlike pressure sore, it may take weeks to develop.
Edges of a Kennedy ulcer are often irregular, and the shape is rarely symmetrical. Bruises, however, may be more uniform in size and shape.
Deteriorating skin may be a sign that organs and body functions are shutting down. Much like your heart or lungs, your skin is an organ.
As the vascular system shuts down, it also becomes harder to pump blood throughout the body. This may cause bones to put added pressure and
stress on the skin.
Until examination is done it is difficult to say what it is.
Please consult your treating doctor he will diagnose the type of ulcer and treat you accordingly.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. Penchila Prasad Kandikattu, Internal Medicine Specialist
