I have 3 growths on my thyroid. They are not cancer, but I would like to know if I should have them removed. They range in size from 3.5 to 5.6 cm. I am beginning to have problems swallowing. My primary care doctor says nothing is wrong, but my weight is going up, my hair is falling out and I have ball spots forming on my head. Also, my skin texture is changing. I was diagnosed with hypothyroidism in 1996 and have been on synthroid 0.05 mg since. I am tired and fatigued all of the time.
