"In November 2002, American Association of Clinical Endocrinologists(AACE) published revised guidelines that provided a new range for normal thyroid function. Until this time, doctors had relied on a normal TSH level ranging from 0.5 to 5.0 to diagnose and treat patients with a thyroid disorder who tested outside the boundaries of that range. AACE encouraged doctors to consider treatment for patients who test outside the boundaries of a narrower margin based on a target TSH level of 0.3 to 3.04. AACE believes the new range will result in improved accuracy of diagnosis for millions of Americans who suffer from a mild thyroid disorder, but have gone untreated." http://www.aace.com/public/awareness/tam/2004/tsh.php
Most of your symptoms don't seem thyroid related, so it wouldn't surprise me if this is more of a down stream symptom from whatever else is going on with you.
