56, male, former athlete, hashi's 25 years, recently switched back to synthroid 175mcg from NP thyroid due to low T4 and high-ish T3. No change in symptoms.
Here's the deal, for the last 6+ years, I run out of energy rapidly, often within minutes. And it's getting worse every year. I can't even do enough exercise to get my heart rate to rise much before my muscles just stop working altogether. Then I have to lie down and recover for hours.
It used to be that "IF" I could get a good gym session in, I'd feel well the rest of the day. I can't get even one set complete at the gym, at any level of exercise. A bike ride yesterday was 4 mph! Unable to put in any effort at all. Walked the bike home, exhausted.
I also am very fatigued and have a difficult time at work. Having to sit and rest a lot.
Heart CT scan shows a calcium score of 0 and nuclear stress test (I was unable to do much time on the treadmill) shows good heart perfusion everywhere.
AM cort tests show 4.2, 6, 7, 10. (scale 6-30)
10mg Pred (taken for skin rash) was a huge help with fatigue and put the problem in mild remission.
