Hi,I am Dr. Shanthi.E (General & Family Physician). I will be looking into your question and guiding you through the process. Please write your question below.
My husband coughed up a patch of brown (1/2 " long) stuff in his mucus. Should I be concerned? He is diabetic, has a pacemaker, has some edema in his feet, and has been coughing a lot for about 4 weeks, ever since he used spray paint working on my dad's house.
