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 Monteleukast 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. The blood snout sometime comes from mouth after deep breathing seems blood tinged sputum.
