Welcome to HealthcareMagic forum valerie,
1st your head symptoms have nothing to do with granuloma
. you have fever
, with headache(thats due to sinusitis
) but only since last few days, if its recurrent issue then the detail investigation can be done like chest x ray
, abdominal USG or CT or MRI to rule out an associated organ involvement. it is very early to say any differential diagnosis. you can consult a good MD physician.
I hope I answered your query. Wish you good health.
