Firstly you should monitor your blood pressure as high blood pressure can be a contributing factor.
Secondly as you have chronic sinus infection with COPD so these are main causative factors in blood in cough.
The fact that you only notice it in the morning might have something to do with the decreased amount of swallowing you do at night. During the day, you are actively salivating, eating, drinking, talking, and "cleaning" out the mouth naturally. At night, however, these activities are suspended, and might allow the blood to collect more. Enough so that you do notice it in the morning when you are awake.
You should use a humidifier in your room.
Take Nasal saline spray and OTC Zantac.
Do oral antiseptic gargles.
Elevate your head with an extra pillow while sleeping.
If blood is profuse then visit ER.
Make an appointment with your doctor ASAP.
Feel free for further queries. It's good to discuss rather than quit.
Your satisfaction is our goal.
