I am suffering from extreme exhaustion. I cannot walk up the stairs without climbing one by one and slowly. I cannot hold myself up because my muscles just dont seem able to hold me up. I am not heavy and have always been fit and well. I get incredibly light headed and feel frequently like i am going to pass out and sometimes i do. I have have ecg's done and blood tests are all fine, i am on the waiting list to see a nero person, or in my terms a brain doctor. I am desperate to get back to work but this is my second week signed off! I have a very active role at work which means i am constantly on my feet and moving around. I have got to the point now of considering purchasing a wheelchair as i feel quite okish, if i dont have to hold up my weight. I am between 8 and 9 stones, 5'1 and losing weight quite rapidly. Any ideas people?
