Ok, I've never really had anything like this before... at first I thought it was just a cold, but I don't have a sore throat, cough, or any of the symptoms really. Basically, I have great trouble breathing and my entire head feels extremely stuffed up. I also feel quite bloated and full after eating meals, and I find it's even harder to breath after eating. Is this a respiratory infection I have or something? Or bronchitis?
