DiveBunny my suggestion is to not start worrying to much. Chances are you just have a bad sinus infection, I can tell you from experience that sometimes they can linger for a while and I would know I have some of the worst sinus problems around. Although it is possible that you may have suffered some kind of trauma to your ear I doubt it, especially if your physician looked into your ears and didn't notice any pooling of fluids in there, at the end of the day it is still ear trauma and whether or not your doctor knows much about diving she would probably notice some trauma or irritation to your inner ear if there was any, or at least I hope so. And clearing your hood is exactly like what Vertgo said on the previous page, its just getting air pockets out of your hood.
