Hope you are getting some help on email.... nothing happening here so far.
The only suggestion I have is make sure you have good humidity inside, maybe put a vaporizer near you when you are not moving about - sleep with one for sure. Then what, cover you face with a scarf when you must expose yourself to cold dry air, and try to limit the time.
Where does the blood come form, is it dried or liquid blood? Is it from your throat or lungs? You needn't answer my questions, as that will not result in me providing any additional help.
The blood is in liquid form bright red and in lump form with tiny red dots . The blood comes from the lung just as if it was phlegm but is blood . Another thing is I usually get tired to fast at times and I tend to sleep more often .
The nasal and sinus areas have rather thin membranes (I am not a medical person) as I understand it and thus a nose bleed is not usually anything serious. I think it is also possible for nasal sinus blood to be swallowed or to at least progress back into the throat - thus could be coughed up.
I am not arguing where the blood comes from just suggestion areas that I hope were checked by a doctor. I have not simple, it will go away, notion about blood being coughed up from the lungs, sounds serious to me.
The fact you can sleep is good, I think.
