I was in emerg for 6 hrs with fast heart , The doc checked my thyroid said it was low 0.2 and that could be causing my
symptoms ..which are .fatique ,panic attacks, palpations , migrains,blurred foggy vision ,forgetfulness,sweating, and some times to the other extreme of feeling cold ,swelling in hands, face , feet, feeling anxious or exterme tiredness. .Sometimes i cant sleep .others i can sleep forever . My family doctor said that the test was normal .He said I was having panic disorder .
