Thanks for the query to H.C.M. Forum.
If I were your treating doctor for this case of high grade fever I would come up with these possibilities , these includes.
as this is the most common cause of high grade fever , cough , blood , phlegm with chills and freezing cold feet .Diagnosis can be confirmed by X RAY chest pa view with clinical as well physical examination by a physician.
2 This high grade fever may be due to malaria with Upper respiratory infection
. Diagnosis can be confirmed by blood film slide as well card test for malaria . Consult a physician and get his opinion .
3 As ibuprofen (advil)+ paracetamol
is not able to control fever so get in blood for typhoid fever
( Widal test
) as fever present with chills .
In my opinion first of all consult a physician and get his opinion.
Good luck. Dr. HET
