Oh my gosh--thank you very much for your insight, support and suggestions.
My daughter got her CT scan today and even though the ENT doctor who ordered it wasn't in today, I had another radiologist give me his opinion...seems it is a chronic infection esp. on the right side [primarily the right nostril is blowing black debris] and that from the looks of it, she has had this infection a long time and needs aggressive antibiotics. Apparently, no "mass" or anything so thank god for that. But my daughter has been having other weird pain today, on other parts of her body, mainly on her lower back near the spinal column and more pain in her face, esp. near her temple so I can't get in fast enough tomorrow, even though this pain may be completely unrelated. This ENT is supposed to be one of the best around here in Northern Virginia, but has a terrible 'bedside' manner. Nonetheless, I will "fire" her, if I still feel she is not really addressing my concerns.
This ENT doctor will read it tomorrow and has indicated that she may want to drain her sinuses surgically, depending upon the scan...which I guess I feel ok about but am still worried about it spreading with anything invasive. Thanks for all you help and welcome any other thoughts you have ..!
