My mom has incontinence issues and needs to wear disposable briefs. Unfortunately, my mom is developing a really bad rash/sore right at the panty line in the upper leg crease. She is an amputee and is wheelchair bond. The rash is developing into a sore, and this concerns me in many different ways. She doesn't have the luxury to stand up and readjust her panties, and with the incontinence issues I'm afraid her rash/sore can and will get infected. We have been treating the skin area with a really good over the counter skin ointment, but as soon as she pulls down her briefs it just breaks open the sore and irritates the skin. I know that the paper/elastic part of the briefs are to blame for this irritation. Does anyone have any suggestions as to what she can wear that can become a barrier against the skin and disposable brief?
