I have a bad cough since April this year. I have been to my GP and have tried all the cough medicines, expectorants and some home remedies like a mixture of ginger, lemon, honey and cayenne pepper but no luck. I am trying herbs now and I do not feel any better. My chest is wheezy and I cough in every minute day and night. I have no chest pains except that when I cough there is also too much mucus in my nose. When I spit this cough there s a lot of saliva which is foamy too that comes out. This is an embarassment, I can t even be with people. When I breath I have to cough because it as if I breathing in this saliva. What could be wrong Dr. Please help me.
