I am sorry, but evaluating WBCs, or protein in the CSF is a highly specialized and technical thing. So therefore, it is up to the doctors to advise you. Some infectious thing in the brain is beyond the scope of us here.

Diabetes and impaired glucose utilization is very common and so naturally more people have this problem.

This is a medical site link that explains CSF testing results.
Has a table showing WBC numbers and what they mean.

If you were given fluoroquinolone antibiotics for your sinuses, be advised that these can cause PN. It is unclear today, if this is reversible. (Cipro, Levaquin, Avelox). Also if you used a netti pot
with unsterilized water, or if you swam in unclean waters, you could have an infection in your sinuses that is very difficult to get rid of.

The organism is called mycobacterium chelonae and can come from
tap water, or any other source. It is being found in US patients with
antibiotic resistant sinus infections.
