Welcome to healingwell, I'm glad you've joined us. I'm certainly not a professional, but I do know that sinus infections can cause pretty nasty headaches, nausea and anxiety. You can suffer from sinus problems without having a blocked nose. How long have you been on the anti-biotics? If you are still in pain and they don't appear to be working then it might be a good idea to go and see your doctor earlier.
It's very unlikely that you would have a brain tumor, it's most likely the sinus, so try and relax and don't worry overly okay? Again, welcome to HW.
