Hi, I had a recurring severe nose bleed for about a week. Lost a lot of blood.  Was examined by an ENT, who found a bleeding anterior artery in my right nostril, and it was cauterized. It stopped the bleeding, but obviously,  I couldnt blow my nose for a week. Its allergy season, and Im very allergic to pollens. Started to wheeze. Ive never wheezed before this. Yesterday I was able to gently blow my nose, and the wheezing stopped. This morning, I coughed up clotted blood. It wasnt much, but it alarmed me.  Is that a natural occurrence after such a large nose bleed? Is it just blood that went to my lungs from the nose? Should I ignore it and just wait and see. Otherwise, I feel fine, just congested from allergies.  Thank you.
Hi and welcome to Chat Doctor. Yes, this is normal for nose bleeding because usually some amount of blood comes into tho mouth so this isn't actually coughing. You should take antiallergic medicines in seasons of pollen. There is no specific prevention of nose bleeding, but it usually stops spontaneously. If this persists you should check blood clotting factors and blood pressure to see is there any disorder. Wish you good health.
