Morning phlegm/blood...please help.?

Most likely its nothing to worry about. If you get rid of the sore throat and phlegm it should all go away. Eat right and get lots of fresh onions and garlic. As for the acid reflux. Eat a healthy diet, limit your sugars, avoid sodas, drink fresh lemons and limes, and don't eat 4 hours before going to bed. Most of your problems can be controlled by the right diet and good digestion.
