Have you been changing up on any of your meds? I had tappered down and gotten off of cymbalta and had problems with always being cold to the point of shaking violently trying to warm up. The doc started me back on cymbalta and now I do not have a problem getting cold. He said it was depresion possibly that was causing the problems, imagine any of us having a bit of depression, I also was losing weight and did not have an appetite and bouts of anxiety, bad. Hope this helps someway. Jim.
Blessed be the God and Father of our Lord Jesus Christ, the Father of mercies and God of all comfort, who comforts us in all our tribulations, that we may be able to comfort those who are in any trouble, with the comfort wich we ourselves are comforted by God. 2 Corinthians 1:3
