What should I do with my cut finger?

Picture taken today(10/16)

On Saturday night (10/10) I touched a metal peice i didn't realize was hot. The skin/blister is completely intact. It is not painful at all. Wouldnt say numb as i can feel if i touch things. I'm keeping it covered and using ointment.

I am not worried about scaring. I just am wondering will it heal with no medical intervention. I don't want to pay an arm and a leg to be told just keep doing what I'm doing.

Any advice would be lovely.

Took the old ones out as the skin was growing over it to much and the stitches were cutting the wound

But do I need more ? It's hard as it's on my palm

Got a small cut on this damn broken handle. Its looks kind of rusted as you can see. I sprayed it with lysol (it was all I could find) and rubbed hand sanitizer on it shortly after. I gotta go see a Doctor anyways it’s been a while… Should I really be worried?

I just scrapped my knee and 24 hours later there's this sticky fluid on my knee? Is this just normal fluid or pus?

Its on an angle like a flap dont know if i need stitches didnt really bleed a ton
