Hello,
Welcome to the ehealthforum and I am really glad to help you out.
From your symptoms it is important to rule out any sinus congestion and inflammation (called sinusitis). The sinuses are air-filled spaces lined with mucous membranes surrounding the forehead, cheeks and eyes. Healthy sinuses allow mucus to drain and air to circulate throughout the nasal passages. When sinuses become inflamed, these areas get blocked and mucus cannot drain. This lack of proper sinus drainage can lead to pressure feeling behind eyes and nose.
Diagnosis can be made by examination, transillumination, xrays, a CT scan, or an MRI.
I would suggest you a, ENT specialist's evaluation for the same.
For anxiety, you should start with anti anxiety medicines.Apart from antianxiety medicines, you can resort to cognitive behavior therapy also. Also reduce your consumption of products that contain caffeine, such as coffee, tea, cola and chocolate.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care.
