I put clear Bacitracin ointment on my infected abrasion wound. I said infected because the area around the wound is swollen, warm, and tender to touch. The Bacitracin eventually turns into pus-like yellow. Did the Bacitracin just turn into pus?

If I leave it even further until dry, it forms a film-like coating on the wound. What is this film-like coating? Should I remove it?
