Polibiotic, opinions and questions

Can elocom be used on the wound after insertion

hello I work in the slaughterhouse yesterday I cut myself on my hand, more precisely the ankle, the wound is about 5mm not too deep, today I noticed a stripe from the wound in a length of about 6cm, I washed the cube with hydrogen peroxide immediately after the whole incident, I glued a plaster and wrapped bandages today, after noticing the welts, the wound along with the swelling I smeared Tribiotic, I have the impression that the stripe disappeared a little, my question is whether I have to go to the doctor or tribiotic can handle it? I would add that the wound and the surrounding area came a little pus, but before smearing with ointment I removed pus and washed several times with hydrogen peroxide, I am surprised by one thing, it does not hurt, it looks not the best, but I do not feel it at all, please help and opinions

Why 1 hole from the earring is red and comes out of it a substance that seals the hole (it looks like such a scab) and after a few hours of wearing the earring hurts (only 1 hole)
