Blood work doesn’t tell the whole story

Well, I saw my neurologist today and he gave me the results of my blood work and my thyroid ultrasound. My blood work came back normal, but the ultrasound shows multi nodule goiters. I was really surprised because I had been tested before with the blood test and it always came back normal. My neuro could not understand why I had so many symptoms of thyroid problems, such as fatigue, sweating, craving carbs, loss of hair, dry skin, and cramping in my legs, so he went ahead and had a ultrasound done on my thyroid. He is a little like House, but not quite so rude. I have to see an endocrinologist and have a thyroid scan done.
