I am a young woman recently diagnosed with hyperthyoidism, likely Graves' disease. This disorder has probably been going on for 3-4 years as I have had tremor for that long & I have goiter. I have had resting tachycardia with arrythmia for at least 6 months, and at the same time I developed an intermittent heavy feeling in my chest (at the sternum, and slightly to the right). I was put on propranolol 100mg due to the tachycardia, at which time the chest feeling became constant. It worsens at night with a dry cough and I occasionally get a bit weezy.
I saw my GP who said I have probably developed asthma and she prescribed an inhaler, which has not helped significantly. I find it strangely coincidental that I would develop asthma right when my thyroid disease was worsening, especially when I have had no history at all of respiratory illness/ allergies. Could this be congestive heart failure? Should I ask for a 2nd opinion or a chest x-ray?
Thank you for your feedback.
