I dont know why and I dont know how this is happening. I had it twice last year in the same place. And now its back again.. I started having chills and fever this afternoon and pretty soon I had my sweats on to keep warm and heavy blankets and socks. I TURNED THE AC OFF! I never do that! I mean unless its in the 70's . I just feel sick now.. sick to mystomach and all that good stuff. Ready to go to bed here too. I will be calling my doctor tomorrow UGH.. I just dont get this.
