Developed a bad cough! Won't go away... Help!

About 2 weeks ago I stayed at a hotel on my way down to Florida. The room smelled horrible... really musty. But I was really tired so I just fell asleep. For the next few days my lungs felt strange and I started coughing.

Now a little over 2 weeks later, I'm coughing on and off all day and waking up at night with coughing fits. I had asthma when I was younger and it feels similar to that. Someone recommended it could be mold exposure. Considering that disgusting smelling room, it's definitely possible.

Can anyone help me diagnose this? Or give me a good way to cure it? I've been waiting for it to go away, but it doesn't seem like it's getting much better.

Thanks
