my husband had a total knee replacement a year and a half ago. He now has this area on his knee which started out like tiny little blisters. He scratched at it. Now he has a huge patch on this knee that scabs and oozes. It seems he somehow got this(whatever it is) on his nose within the last few days. We have seen his knee doctor & we have seen his family physician to no avail. He has an appointment to go see a skin specialist which won't be covered by medicare. I am wondering if anyone finds this familiar and if you were able to find a treatment and if so would you please share this info...Thanks, di007
