Do you have a humidifier? If not, keep a large pan of water on your stove and heat the water until it gives off steam. You can also go into your bathroom and turn the shower on the hottest water and sit and breathe in the steam. That would help break up your chest congestion and your sinus congestion as well.

If you can, try the honey on a wash cloth and breathe it in, it will help reduce your coughing. When coughing too much you can pull the muscles in your chest and/or back. A warm heating pad will help with that pain too.

Have you been to your doc yet about the cold? Could it have turned into bronchitis or even pneumonia?

I hope you feel better really soon. Take care of yourself ICP.
