Have you ever heard of chronic fatigue syndrome? My aunt was recently diagnosed with it based on what she was experiencing.
No i have not. What are the symptoms of the illness? 
Essentially for her - she was not able to do daily chores - going to the grocery, using stairs, etc. and rest did not help.
That would be very challenging. What are the possible cure for this?
The doctors say that there is not a cure, but other people with this find that activity regimens and physical therapy help.
