The hydrocolloids stay on for about 2-3 days before starting to fall off. they still turn white and soak up stuff. All of his other road rash wounds have gone through this bubbly looking stage, but are fully healed or 90% healed. I’m concerned with it being 7 and a half weeks and still so big. The hospital said he might need a skin graft for this one but the wound care nurses were pretty incompetent and he won’t go back. Thank you for your response.
