Hi welcome to Health care magic forum. Your father was brought to the hospital with,multiple myeloma
, Vascular dementia
, and epilepsy
He was brought to the hospital with chest infection
6 weeks ago , and he was walking at that time. But you also agree that your father was sick.
It appears that your father had previous diseases and present chest infection, made him debilitating, and slowly deteriorating. probably due to resistance of the organisms to the present treatment.
Of course i don't deny your openion of side effects of the fevilemed due to its spectrum of side effects.
what you have to think of now is what to do, but not why is it. Have an open talk with your doctor and decide what can be done at this stage.
Wishing for a good out come, and thanks for calling.
