question: i have extreme fatigue, pains flashing throughout body; chills and night sweats with pools of sweat in bedding, joint pain sometimes with swelling and sometimes without; dizzy and lightheaded with nausea all the time and sometimes throwing up. This happens alot when I stand up or make a sudden move. Sometimes I can just be standing there and get suddenly chilled and then sweat pouring off of me and about to pass out. Fogging brain. Use to have a great memory but don t anymore. Neck and shoulder pain constantly. Feels like bricks sitting on me all the time. No appetite. I am 53 year old female and have always been very active.
