I need help, I just noticed that Jake has an area on his rear foot that sort of looks like a callous, it's odd looking. I felt it today and it feels like there is fluid and when I pressed a bloody fluid came out on a tissue. It may be a spot wear there is pressure when he lays down. I know there is a word for something like this......I have searched but can't find it. I think I remember a poster having dealt with one recently on an elbow. Jake goes in next week for a routine exam and fecal and I need some help. Can someone please tell me the medical term for it so I can research it....please.
