I have had an interesting day!! Took my eldest son to his university open day and my sister offered to come with me as my hubby working. I gratefully accepted as it was a 150 mile round trip a d fatigue muscle pain bad at the moment. I only see my sister infrequently but her help today was gratefully recieved. Anyway to get to the point she was diagnosed hperthyroid about 5 yrs ago, has been on carbimazole and beta blockers. Then was well for awhile but has had to go back on beta blockers as resting heart rate was 120. She was asked by her endo for family history and mother had Addison disease a sjorgen disease. I am fighting for hypothyroidism diagnosis and my sister thinks I should go back to my gp and tell them about mum as she thinks there is a link. Is she right?? I have never been testedfor adrenals or thyroid antibodies as my gp thinks i'm 'normal'!!
