I had my first "normal" blood test result about 4 weeks ago since being diagnosed in Nov 2012. For the past 10 days or so palpitations have been regular daily I feel fatigued and feel some of my symptoms are returning. I am wondering if my levels have changed or am I just tired? I also suffer from Plantar Fasciitis which has definitely got worse. I have that horrible feeling is it me or my thyroid?
