When I woke up this morning I am coughing up brown mucus also when I blow my nose I have a cough my sinuses hurt and my throat hurt. Help?

See doctor. It seems like you might be dealing with a bad sinus infection. You need to be seen by your doctor today. Tobacco use sets you up for this sort of thing, damaging the cilia in your nose that helps prevent infection. It's a sign that you need to stop smoking.
