Hi- just recently I had developed a few issues that leave me concerned. Issues including; change in vision while looking at the same time (almost like its becoming double? it is extrememly hard to explain), shakiness ...EXTREME... in my hands about an hour after I wake up and lasting till I go to sleep. My legs have now also begun to shake very bad to where i cannot walk down the stairs without almost falling from being shaky and becoming dizzy. I am very nauseous, no bowel movements, ZERO appetite and if i do eat it makes me even more naeusous. Every other issue in the book I am experiencing out of nowhere. What could this be?
