My step sister is in ICU from a diabetic coma. When I found her, she was barely breathing, and she was probably in a coma about 5 hours before help arrived. Now she has been in the coma around 27 hours. The doctors are talking about brain damage from lack of oxygen. When they tickle her feet, her toes go straight instead of curling up.
How long does people usually stay in this type of coma and what's with her toes not curling up?
