Should I Apply Soframycin To Treat A Recurring Nose Piercing Bump That Bleeds?

I m having an nose piercing bump over a month now, and as the time goes it eventually gets bigger and smaller and it always bursts out with blood, as being an 13 year old school girl that s embarrassing when someone asks you what s that on your nose. I have recently purchased a skin cream called soframycin and my family suggested it. Can you please tell me how many times I have to apply it and how?
