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.
