Should I be concerned that there is always blood when I blow my nose? For 10+ years now I’m a 32 year old female, and have been having this issue for over 10 years. I did a lot of cocaine as a teenager, to the point where my nostrils would be super irritated and  low functioning much of the time. I have been clean and sober for over a decade now, but ever since those days, every single time I blow my nose there is some amount of blood that comes out of my right nostril. Sometimes a little, sometimes quite a bit, but I pretty much blow my nose gently every night after I wash my face and it’s always bloody from that side. What are some possible explanations for this? Should I be concerned?
