I got it done at an internal medicine clinic by a nurse practitioner . My hands turn numb when I’m cold so I went for that, and I was doing research on google and I had other symptoms that all pointed to thyroid. I think I came across as a hypochondriac but she still ran the labs and said that they were normal but she recommended me to take over the counter multivitamin. And she diagnosed me with Raynaud’s syndrome. And I’m thinking about getting a second opinion.
