It's official. I've had larygitis for 3 weeks.

It started off by babysitting my nephew, whom had the croup, and coughed and sneezed in my face.
I went home and in the next few hours, got a stuffy nose, chills, sore throat, headache and just felt downright tired. I also developed a cough (couldn't classify it as dry or productive but in between). I began to lose my voice until you could barely hear me. It's been 3 weeks and I still can't talk! Only one side of my throat hurts to swallow, and that isn't even the entire time, it only hurts occasionally. I've been drinking tea and soup and have a vaporizer on during the night but every morning I wake up and nothing has changed. My voice isn't as cracky but it does fade in and out and gets worse the more I speak. I don't really even have a cough anymore, two days ago it was a very dry, hacking cough. Now I barely cough and sometimes spit something up that looks like a few small lumps or drops of mucus but nothing like what I was spitting up before. What could it be?
