Kann Sinusitis wiederkehrende Fieber verursachen? Oder ist es Blutkrebs?

From last 2 weeks I’m suffering from sinus problem, mild cold and fever… Almost daily I get low grade fever around 4 pm and it goes away by itself around 9-10 pm without any medication..

I will visit my GP in a day or two… But my concern is the fever which is coming and going away automatically… Is it blood cancer or it’s common for sinusitis to cause this kind of recurring fever ??

My English is not good but I hope you guys will understand

Thank you
