I have had an sinuse infection since sept on and off I was given steroid shot in sept which at that time I was dx with diabetic due to lab work showing 356 bs non fasting but I also had a white count of 20 thousand took antiboctics cleared up some but was back with in weeks white count up, now when i start to get high white count by bs goes up, I have had sinuses drainage with color, headaches neck aches, I had ct scan which states 1. Bilateral ethmoid, r sphenoid and frontal sinusitis,2 Right Sphenoid mucus retention cyst, approx 1.5 cm in size 3. Mild Rhinitis. Oh and not to mention if feels like the right side of my head could blow up, and visual problems and ear ach and teeth hurting, but all the teeth that hurt has had root canals, so I know it is sinuses. My question is could this cyst be making blood sugar be up. I am going to an ent on the 19th but should I try to get in before? And how serious is this?
