Having been through so much with my dad, having medical knowledge in these situations is a blessing and a curse. I absolutely know that my dad's care team grew to hate me because I was pointing out something obvious to them, or asking legit good questions, on a weekly basis at a minimum. I am glad we can be good advocates, but so much falls on our shoulders as a result and it is rare to find a human health professional that is willing to hear us out, or even treat us like maybe, just maybe, we might know something or understand what is going on.
I know insurance plays a role in what they can and cannot do (ie maybe your hubby would have gotten a full abd aus, but insurance put the kabosh on it), but when it comes to simpler things I will never understand how human med functions at what is supposed to be such a 'high level' but also in ways that has us lowly vet people raising eyebrows.
