Help Me Please

I haven't been on in a few days due to sickness, I have been quite miserable. If that is possible lol.. My Fibromyalgia has taking a back seat. Out of the blue 4 weeks ago My nasal passages swelled up inside & have gotten worse since. There is no opening inside my nose. I can't breathe, no meds are helping. My face hurts, & my ears are stopped up. I went to the Doctor yesterday and My Ent said there was nothing showing on the Cat Scan & he didn't know what was going on, & that is not what I wanted to hear, but he is sending me to a Neurologist to get a Ct Brain Scan & now I am scared. He said it was possible a neurological problem. What does that mean? Fall is My favorite time of the year & I can't seem to get to feeling better with the sinus symptoms so I can enjoy this beautiful weather. I have had it for over a month now. Its making me more miserable then the fibromyalgia. My sleeping has improved, found the culprit that was keeping me up. But The sinuses has made me so extremely tired. Help.. I am using the Netti Pot alot and humidifier, & etc.. I don't know what else to do. My nose is burning & in alot of pain & loads of pressure from the intense swelling. I have no congestion, no sneezing, no coughing so what could it be? Is it Allergies, or Chemical Sensitivity or Yeast? So my dear friends be patient I will write you soon as I can. I am just so very tired & sick I don't feel like being on the computer right now, I can't concentrate enough to write. Thanks for all your support, I will be back soon. If you know anything about sinuses relief please all comments will be appreciated. Your Friend Pamm
