vaseline, neosporin, gauze (Nw las vegas)

I am in dire need of Vaseline regular scents or dies in it for my two ulcers there on top of both my feet that have been let to dry out by the hospital and now it’s very painful and Neosporin with lidocaine in it and some gauze wraps there’s nothing I can do until I get my school money and that’s two weeks away. It’s been two days without any covering on them and it’s very painful.
