Thanks for using health care magic for posting your query.
I have gone through your question in detail and I can understand what you are going through.
From what you have stated it appears that your husband has again developed an infection, probably a bacterial infection. If he has had pneumonia
in the past then he is likely to have it again as well. You should show him to a internal medicine doctor who would like to X-ray him and if necessary give some antibiotics. He certainly needs round the clock cover of paracetamol
Hope I am able to help you,
If you have any further query, I would be glad to help you.

Wish you good health,
Dr. Srikanth Reddy M.D.
