Is PVS related to CFS?

Hi I am newly diagnosed in the summer with cfs. I just know that if you have flu like symptoms for a long time they called it post viral and then if this doesnt go away in 6 months and all your blood tests for other illnesses comes back clear then it might be cfs. You are on the right website but there are loads of information on the web for you to find out or really quizz your doc as my kept using the above term until I asked her about cfs, then she said 'oh I am glad you said that because the specialist I am referring you to is a cfs clinic.' Until then she only ever used the term post viral...best of luck. x
