I had some blood work done for my endo, who treats my osteoporosis and also has been watching nodules on my thyroid for like, 7 years. I used to have scans done every 6 months/bloodwork, but nothing ever changed, so she said it wasn't necessary. I am actually not seeing her for a year, now since my osteoporosis has improved so much with medication, I don't need to take the meds for year. I don't think the blood work had any thyroid tests, though. If I don't see a change in 2-3 months, I will definitely go see her. She's a runner and gets it.
