My mum has got stage 3 lung cancer and they told her she has 12 month with chemo or 6 months without, that was last March.  She has been doing so well on the chemo but i went to see her last weekend (I live over 200 miles away) and as i have not seen her for a couple of weeks i noticed she was alot more confused and extremely tired.  My dad has called today and said she is constantly sick and has not got out of bed for 2 days. I have told him to call the McMillan Nurse who is coming today.  I dont know if this is a bug or something i should be concerned about and need to travel to see her tonight.  There is only me as my sister died suddenly a couple of years ago. Any advice?
