What would happen with a total occlusion of a diagonal artery of the LAD? But no occlusion in the LAD itself? What is the treatment for a diagonal blockage?

I recently had a coronary CT angiogram and nothing showed except a calcium score of 6, a mild to minimal stenosis in diagonal 1 and a moderate 40 to 59 percent stenosis in diagonal 2.

I have had a nosebleed every day after soccer practice for the last four days. The nosebleeds occur for 3-7 minutes and happen both during practice and in the shower after practice. I have a sensitive nose and this has happened before when I was younger. I am 13 years old, bleed from the same side (right), and have normal blood pressure. What could be causing these nosebleeds and what should I do?
