EXACTLY why I would push for more bloods and a deeper look into ...
It is well known that chronic inflammation and /or infection will produce their own "anemia" type syndrome by supressing the bone marrow
SO ... you have a major infection ... AND your body is going anemic = YOU HAVE NO ENERGY TO START WITH .....AND NO RESERVES
IF NOBODY IS LOOKING AT BLOOD RESULTS ... ain't gonna get found !!!!!!!!!!!!!!
I am also a veteran of post op abscess infection
(( and treated thousands of vet patients for systemic infections ...
NEVER had any other life experience as severe as that
Had "rambocillin" and IV supports for a few days ... then started to feel better
Gladly mine was treated ASAP and short lived .... BUTT still it was a major occurence in my healing process.
KEEP pushing the docs for answers and curative measures
BE the squeaky wheel until YOU are back on your game
