Re: could extreme fatigue be heart related?
I had a MI fifteen years ago and I do have CAD. I have had something very similar to what you describe for the past three years. When my fatigue first came on I could not function. MD order a cardiac cath. and found everything was not only OK, but actually better than the previous cath. I went to an endocrinologist who diagnosed Hashimoto’s Thyroiditis. My thyroid meds were adjusted but did not help. I was forced to retire because of the fatigue. I have had stress tests, echocardiograms, and other cardiac tests since then. I have been to three endocrinologist. The tests show nothing wrong but the fatigue persists.
Last year I was diagnosed with Glaucoma and was treated. I also have leg aches in the calf muscles. I have also had tests on my legs which show no problems with my circulation. My latest MD thinks it might be depression. He did prescribe an anti-inflammatory for my leg pain. I have also tried various allergy meds with varied results.
Have you seen a cardiologist?
