My daughter (22) woke up this morning, went upstairs to take a shower and threw up and on her way back to her bed shaking. She got up a bit later to make her some soup and had to lay down because she thought she was going to pass out. When she layed down she noticed her body had a light sweat and she is shaky when she is not lying down. I thought it might be the flu but she said that she has never felt this way with the flu.... Her symptoms are light headed, dizzy, shaky, sweaty when she gets dizzy and a headache.....but only when she isn t laying down. Any ideas or suggestions?
