I don't know whats wrong with me. For the past few weeks now I have been getting worse. I am permenantly cold and shivering. My hands keep shaking and I am so tired to the point I fall asleep all the time, even though I go to bed early. I've got bruises on my arms and legs and I don't know where I have got them from. I am eating well so its not diet related. Over the weekend I felt as though I couldn't physically get out of bed. I really want to do things but I physically can't do it. I am sat here with 2 tshirts, my jumper and a jacket on and I am still shivering. I don't feel unwell otherwise and I am eating ok. My fingernails are bluey coloured as well. Any ideas? I would go to the doctot but I daresay they will just tell me that it is a virus and to just rest!
