About a month ago, I had a really bad cold, and while I had it, I couldn't really sneeze. I could occasionally, but only when I looked at a light, and that didn't guarantee anything. This continued for a week or two after my cold was gone. I was able to sneeze normally for a few weeks. Now, it's back, and I have no cold or other illness whatsoever. I can sneeze sometimes, but usually I just get a sneezing sensation, but nothing comes. I have a doctor appointment in a week and I'm going to ask about it, but I'm getting worried that it might be something with my brain.
