I have been having bouts of being freezing cold. I will get under all of the blankets in the house with a heating pad and still be cold. I also am having a hard time holding a book because my fingers start tingling and hurt and my feet and legs will do the same thing if I lay in the same place longer than a few minutes. I have also been experiencing spasms in my throat, it feels like something is stuck in my throat, but there isn't anything there. And the latest occurred today. I was taking a hot shower because I couldn't get warm and i spontaneously vomited. I wasn't feeling sick to my stomach or anything, it just happened. I didn't feel sick afterward either. Has anyone else experienced anything like this? I haven't changed meds or supplements recently.
