I don't want to go into all the gorey details, but I can say that it has so far successfully cleared up my sinus problems. They found, through Xrays, that I had a bone perforating my sinus lining, and that's probably what led to all the infections I kept getting. They had go in and saw this bone off. I know, fun right? I get a bone graft next time. That was supposed to be today but they didn't get to it. I guess that'll be next week or so.
The good news is, I haven't had any sinus problems since they did the initial work! I can drink Dr Pepper again without it hurting me!
