If you have a fever, there is a good chance that you have a bacterial infection. What color is your mucus when you blow your nose? If it is yellowish or green, you need antibiotics. If it isn't, you need an expectorant, which means it will break up the mucus and junk and help your coughs be productive.
Spray your house down with Lysol (or an equivalent). Don't forget door handles, the toilet, and your phone(s). Do this even if your mucus is still clear.
There are homeopathic things you can do, but they are hit and miss and not as effective if you have a genuine infection. Sometimes we need modern science to get us through.
