I agree with others test esters are not natural, I am sure and endo can explain the physiology even though drs love stable levels its not natural/normal. but I would say 1 get an EKG and ECG make sure your not doing damage with strange rhythm or a carditis . funny your dr hasn't addressed this concern.
2. Perhaps try more physiological test ie cream or test base or nasal test that levels will lower in the evening.
3. did you get covid around the same time noticed symptoms ~3 months within infection? folks always think everything heart is vax related when its pretty clear infection causes similar things but 100X worse. but of course issues do arise from covid vax aswell. no need to derail thread about that stuff but something to be aware of.
4. had similar feeling on HCG very quickly and ive never had the explanation other than it happens.
5. yes I think drs that know what they are doing dont shoot for numbers and refer to ratios of estrogen with T etc.
6. see an endo, but you dont want heart issues man esp if something is causing enlargement and perhaps is just enlargement ie pericarditis due to edema from androgens. perhaps had it before perhaps viral infection made it worse and then more fluid retention causing the issue. basically restricts the heart so it has to beat harder to work even though your BP is normal.
cortisol levels checked? take magnesium? taking a lower dose make symptoms noticeably less?
more im thinking more it sounds like could possibly be carditis and sometimes tough to diagnose...have your dr explain why its impossible thats the case
