Hi I am a 23 year old receptionist who freaks herself out! Last friday I came down with a stomach virus or food poisoning, I thought I was hung over at first, but I was throwing upa nd had diarreah all day a long with a mild fever, saturday I felt fine, a little woozy from dehydration but ok, gettin ready to go out I suddently got a pain in my neck, that shot to my upper back, all night it hurt to turn my head side to side and bring my chin to my chest...Sunday I felt okay neck was still sore, monmday felt the same eating normally and everything, and drove 3 hours home when I got to my house, I had this weird headache, kind of like a dull heavy feeling like when you spin around and around and get dizzy its that kind of feeling....I of course look symptoms up and automatically think the worse, I havn'et felt myself in a week now, and its all I thinka bout, my mom says that just making it worse...I've read it could be anxiety, tmj, anything, and I worry its something brain related, I am a hypochondriac, and a worry wart...I do still have the pain in my neck and i'm a little more tired then normal, could this still be from having the stomach virus last friday?? Im tired of thinking about this and have never experienced anythign like this before I just want to feel better...Anyone who could offer me some advice, would be greatly appreciated..
