hi, i'm very concerned about my sister who until five months ago was a very active and hard working girl. She began feeling tired just doing the most basic tasks and this was accompanied by constant nausea and muscle weakness. She felt dizzy and that she had trouble focusing visually. Initially the nausea subsided when she lay flat but the fatigue was not relieved. She had pain around her diaphragm area and neck pain. The diaphragm area was so painful that she has not been able to wear her bra since. She has had every blood test under the sun and all seem normal.She lost 2 stone in weight and has had to stop working and was even admitted to hospital for 2 weeks but to no avail. She has had ultrasound scans of her abdomen and ct scans of her neck, barium enema -all normal. She is awaiting a brain scan. She has recently gained about a stone which has been down to my mum who is really trying to feed her up. The nausea is 24 hours a day still but she says that she feels hungry all the time.But the nausea does not go away even when she lies down now.She is 40 years old and is feeling very depressed and says that she can not cope with feeling like this any longer. I have read a lot of info on CFS and it does seem very similar but the nausea doesn't seem to be mentioned often as a symptom.Can anyone help please?
