I guess I was lucky that the worst symptoms showed up months before a physical. My GP didn’t notice my tremors but the nurse did while taking my heart rate. The GP wrote it off to some inherited cause of a tremor. The thyroid score on the physical initiated the visit to the endo. So looking back I can see that the tremors were there for months and months before the nurse noticed but to a smaller degree.
I will take later than never on the diagnosis.
