Since my thyroid levels are normal, my endo ruled out thyroid as the cause of my muscle aches. We considered the possibility it was parathyroid related for a while (because my vitamin D and PTH levels were low) but my calcium levels are normal so that was ruled out as well.
Since I am having a variety of symptoms (headache, stomach pain, nausea, joint pain, fatigue, general sick/weak feeling, etc.) and my thyroid levels are normal, we are starting to consider other diagnoses including POTS and Addisons Disease. I’m getting some blood tests done tomorrow so we’ll see. I’m not excited to potentially go on another autoimmune diagnosis journey ugh.
