Hello,
Thanks for the query to H.C.M. Forum.
Blocked nose, mucus from nose, difficulty in breathing, throat pain,
cough with or without phlegm,
These above mentioned symptoms are suggestive of
allergy of respiratory system with super added infection ( if expectoration or phlegm present).
Same is in your case.
Now blood is there, that is cause of concern, may be due to,
Forceful expulsion of mucus from nose,
Due to some disease in lungs,
Blood disorders.
So please get in blood examination for C B C ( COMPLETE BLOOD CELL COUNTS), E S R ( few say nonspecific ,if very high indicator of some chronic infectious disease).
Although it seems that you have allergy ,but consult a physician and physical examination will reveal the exact type of disease.
Hope I have answered your question successfully.
If further any question I will help.
Wish you a good luck.
Dr. HET.
