Just had results from blood test yesterday via telephone consultation with GP. The results for TSH levels were 0.4 which he said were at an optimal level. I then explained I was still feeling tired and sluggish most of the time with leg and joint pains. He has refused to adjust my Levo medication but has agreed to further blood test to test my vitamin and mineral levels. Is he on the right page with this or do I need to seek a second opinion? I'm on 75mg of Levo.
