I am a paraplegic, with pressure ulcer on left-rear end. It s been there for two years, and I am currently applying a cleansing solution as well as healing solution that was developed at the University of Ga. for treatment of burns, cuts, scrapes, and most important, PRESSURE SORES (decubitus ulcers), back in 2009. I am keep pressure off the area as much as possible. Any other recommendations as to healing?
