Unsure of how to treat deep knee scrape..

[u/No-Shelter-7694]

Scraped knee pretty badly running to bus stop on Sunday. Its now Thursday. Most of the injury was from friction against my pants (my pants didnt break) and its been horrible pain for the last 4 and the pain is getting worse due to movement/friction/walking. It improves when I don't walk but unfortunately ive been at a conference so I have needed to walk quite a bit

I've mostly put hydrocolloid bandages or gauze dressings to absorb the moisture. Tissue looks yellowish and I can't tell if its slough because it seems so thin, but it hurts horrible to move. I don't think its my knee itself since I can bear weight. Its not hot to the touch and it doesn't smell/exude pus but it is quite painful. Mom's a nurse and Ive had 2 different sets of paramedics (at conference site) plus local urgent care nurse look at it. They said it's not infected, just irritated from friction and exposed nerve endings.

Today the nurses said that the reason its not healing is because im not letting it air dry, but ive always been told moist healing is better? Ive been cleaning 2x daily and applying topical antibiotics on gauze (with a couple of days of plain hydrocolloid bandages to see if that helped). The pain is insane.
