Prednisone Alternatives?

Currently on Claritin, nasal steroids, and have tried sinus rinses before. I got an allergy test and CT exam, saw very little inflammation and got no allergies except for a few molds.

When I was on prednisone, everything came back to normal. It felt like I was living again... Did anyone have a similar experience they can share or a proper alternative they found to prednisone?

EDIT:

My symptoms: Right now, with the spray steroid and Claritin I still have sinus pressure/headaches/brain fog, fatigue, and nasal drip. The only thing the spray and Claritin are doing is opening up my nose to breathe just a little more. With prednisone, everything went away. I do drink plenty of water, exercise, eat healthy, and run.

The pressure is in this general area

EDIT2:

Went to a neurologist, getting an MRI and another blood panel done for migraine related issues.
Also wanted to note that the brain fog and tension headaches generally come 2-4 hours after waking up.

EDIT3:

I am borderline on Vitamin B12 levels (270 pg/mL). Will be taking pills soon to see if anything changes. Will also be getting a MRI scheduled soon. Will update again soon!

EDIT4:

MRI has been done, nothing found. As much as that is good news, it also just makes things more confusing. Been on Vitamin B12 for about one week and have not seen much change. Will be trying cold showers for 4 weeks as well to see what that does. Will also be getting new prescription glasses. Will update soon!
