I just came back from break at work when I started feeling nauseous. My legs and arms felt weak and a little shakey when I walked to get water. My head started to ache and weird pain happened to my throat. Not a sore throat but a dull pain to the touch and movement, like muscle pain. My eyes have been aching staring at a paper to copy info to the computer. I don't wear glasses and recently had an eye exam where they said I'm not quite to the point of needing them but will in a few years time for being far-sighted. I did not have anything to eat this morning except for a coffee and had a tough time sleeping, resulting in about 5 hours (not too bad). Just curious if this is any real concern? I'm still nauseated and still kind of light headed, and my eyes feel very heavy. Still little shakey. Also I had blood work done a few months ago for regular checkup and my thyroid was on the border of irregularaties.
