Both EG & I went through this gawdawful illness
Sounds very similar to what your OH has.
I went the antibiotics route.
Then loads of supplements
to build up my immune system.
As I am already immune compromised,
I loaded up on the garlic,
honey & apple cider vinegar.
EG only used ibuprophen for the inflammation.
He did continue smoking
high quality roll your own tobacco
that does not have the additives
that cigarettes have.
There were many nights when I propped myself up in bed
and actually slept in a sitting up position.
I talked to my local health food shop owner
who advised that next time,
use a few drops of tea tree oil
in a bowl of boiling water,
with the towel over my head routine,
similar to grneyelady.
No need for wrapping packages up,
as the oil will disperse.
Note: Should also help his complexion, as we use tea tree oil regularly for the occasional spot.
That is "pimple" for you yanks & rebs !
PS We, too, thought that this might have been related to chemtrail spraying,
as we had aching symptoms, similar to flu, in addition to respiratory propblems.
I swear, sometimes I felt that I was breathing under water !
