Thanks for your response. Brian I didn't know that fearing for my life was playing wolf. I get what you are saying but this is the same guy that looked at my white spot and stated, " it looks benign." I'm just nervous because I didn't know a person could tell a cyst from a tumor on a CT scan. I don't know very much at all and my fear is obviously getting on people's nerves. I've only had the one encounter with this guy so how have I played wolf with him. I wasn't freaking out on the phone with him. I just simply wanted to know what the cyst. I have you posting to remain calm and a cyt is just a cyst. I have the next poster telling me to run to another office asap. I'm just at a loss as to how to act and where to go. I feel that I have worn out my welcome here and will just try to deal with this myself. A white spot and a cyst?! I don't know how common maxillary sinus/nasal cysts are....
