Thanks for your comments. Sorry for my late reply; I forgot I had asked this question...
My son does see Dr. J and he said that it is not a problem because the other thyroid numbers were normal. I plan to have him retested later, however.
Frango - were all of your sons thyroid numbers abornal? Did you have your son treated through Dr. J? Just curious, who is your LLMD? Did his thryroid symptoms improved with lyme treatment? How are his lyme symptoms now?
tropicalsun - My son is currently on Bactrim, azithromycin, Mepron and artimisinin. We have seen improvement in his fatigue, but not really his other symptoms, yet. It has been 5 months so far. His night sweats have diminished as well.
