That's pretty much it. I've had it twice and it doesn't get easier.

I'd got to a pharmacy and explain your symptoms. They should be able to come up with something that will help you through it. I'm guessing something like Mucinex.

If you have a fever I'd probably make a doc appointment. Pneumonia can be caused by either a virus or bacteria. If it's the latter they can probably give you some good antibiotics.
