Can Sinusitis Cause These Symptoms?

1. Constant brain fog.
2. Short term memory problems.
3. Word finding troubles.
4. Lack of interest in things.
5. Anxiety/Panic Attacks.
6. Obsessive thoughts.
7. Tinnitus in my right ear.
8. Pressure between eyes and bridge of nose.
9. Hard to breathe through nose.
10. Trouble concentrating.

I'm not congested and nothing comes out of my nose when I blow.

I suffered a TBI in June of last year and have had 3 CT scans and one MRI that all showed Acute Sinusitis on the right side. My TBI symptoms recently have gotten worse over the past months and I'm wondering if it could be caused by the Sinusitis getting worse...since the sinuses are so close to the brain. I started taking anti-biotics for the Sinusitis awhile back but I ended up being allergic to them and broke out in a serious rash on my chest. I noticed the symptoms I described started to get better and then suddenly got worse after I stopped taking the anti-biotics. It could have been pure coincidence. Anyways, just trying to get to the bottom of things.

Any help or incite would be great.
