HI, Welcome to HealthcareMagic forum,
Blood in phlegm
can be the same thing that may be leaking from your nose into your mouth in your case, but it can be a symptom for so many diseases on of which is lung cancer
itself has a lot of adverse effects on your respiratory system
, so try to cut down on it and preferably quit. Your bloody nose may be because of rupture of a blood vessel
in the nose which can be due to various reasons like you meddling too much inside your nose, very high blood pressure, or due to the nasal sprays also. It is advisable to get some basic blood tests which your physician will order and a Chest X ray. Wish you good health. Take care.
