Have you had sinus problems before?
Do you have a fever?
Is your face visibly swollen?
No Major sinus problems, just colds here and there
Yes I feel that I have a fever.... cold chills
I don't think its swollen by the looks.
Since you have a fever and severe symptoms, I do think imaging is indicated. A sinus CT should be done to confirm the diagnosis of sinusitis, especially since you do not have a history of sinusitis.
Severe sinusitis should be treated with both antibiotics and steroids(either steroid nasal spray or oral prednisone). I would recommend using steroids in your case to decrease sinus inflammation.
People with sinus disease and facial swelling need to go to the ER( sinus infection spreading to facial tissue is a medical emergency). Since you do not have facial swelling, you can go to an urgent care clinic and be evaluated. If you start taking prednisone today, you should feel a lot better very soon.
I hope this is helpful to you.
