Wow, what a story you have about the pregnancy. Bummer to say the least.
Your symptoms don;t sound all that unusual for Graves’, One concern I would have is your vision being blurry. Have you seen a Ophthalmologist? The eye problems must be treated separately from the thyroid.
I know what you mean about the insurance. I had just gotten insurance when I was diagnosed with the eye disease and they called it a pre existing condition. The med bills eventually piled up to around $20, 000 that I had to end up just blowing off since I couldn’t work at the time.
All the best, Bruce
