Phlegm mixed with some blood could be due to irritation of the nose, sinuses, or lungs. Swallowing this blood will cause it to end up in your stool.There could be many reasons why you see blood in your sputum. Ranging from dry sinuses causing bleeding and post nasal drip, all the way to a negrotizing infection in your lungs.What ever it is....its not normal and the remedy will not fix it here. It will be in your doctors office.
