Hi Just wondered if anyone has the same problem with CFS. After a recent holiday I have been feeling really dizzy with loud ringing in the ears. If I stand still I feel like I am not here it is an awful feeling. I have also felt really tired and been sleeping for hours. Last week I felt really shaky all over and yestereday my legs just gave way and now will not hold up my weight which is only 7 stone. My calf muscles are really painful and feel tight also. I guess I have over done it again. Does this happen to anyone else on here? Thank you for your help it is very much appreciated.
