I used to smoke and quit about 5 months ago. All of a sudden I had the worse mucous anyone could have. It was like gum in consistency and when I pulled it out of from nose to spit, I had blood too. You're probably just hurting the nasal passages. It if were anything serious, you would have bright red blood when you coughed. Not to mention, shortness of breath. Have your doctor do a chest xray anyway, it doesn't hurt and it relieved my worry. Good luck.
I notice there is blood in my spit and I am a litle concern I dont know what it could be I have a little discomfort on my chest please any suggestion ?
