Thanks for writing in to Healthcare Magic!
Your clinical picture is almost confirmatory of lymphoma
how long the trouble has been?
These patients progressively get depleted of immunity and once sepsis
come in the scenario the outcome is very bad.
Please get a review with the hemato-oncologist
and get the diagnosis confirmed with additional work-up and receive suitable chemotherapy
If you have any further query please let me know I would try to answer it for you.
Wish you a great health!
