Much to our relief, the angiogram showed that there was nothing wrong with Dad's heart. I'm so grateful, as I'm not sure what the future would have brought had there been complications with the ol' ticker. That still leaves the question, however, of what is causing his arm to be in pain. He's got an appointment with his family doctor in Vernal, who will hopefully run some more tests. I suggested he have an x-ray, thinking perhaps he's done something to it without realizing. Dad seems to think there may be some nerve damage or the likes. As frustrating as it is to not have answers, and as painful as it is to not have relief from the discomfort in his arm, I feel blessed and so very thankful it's not heart-related.
