I am getting slight blood in my left nostril from months during blowing or cleaning. Last month also there were blood streaks in cough so I consulted a general physician and was on antibiotics for 1 week followed by test of chest x ray, cbc, esr and sputum culture. All the test shown up normal so I was told to discontinue. But still there is very minute bleeding only in left nostril. Went to ent clinic was on medication for 3 days with montelukast tab. Xylometazoline nasal drops and liquid paraffin. But after few days still I can see minute blood from left nostril which seems very red and little inflammaled without any pain.
