I'm sorry I have a new question. My mother is bed ridden and she has a wound on her coccyx and it had healed. She was wearing a Catheter but he had to take it out because it kept causing problems but now that she is wearing diaper I am having a hard time keeping her coccyx dry and the wound opened back up. What can I do? My mother lays on her back so when she has to go to the bathroom it goes to her bottom and it opened her wound back up. I would like to know if there is any way to prevent that from happening. We move her but she always goes back on her back.
