This is Dr. David
are you having a nurse come to visit you routinely?
are you bed bound?
you need silvadine cream I think
are you allergic to sulfa creams?
you really need to be turned frequently so you are not still laying on the same areas all the time worsening your bed sores.
it sounds like you need to be in a nursing home and have 24 hour a day care
are you living by yourself at this point?
I would make sure you get your wounds evaluated by a wound care nurse or a doctor for treatment.
