Hey,
I had my nose done by Mr G, on the 28th January, I got told to remove the blanket the next day. I would say remove it and let the air get to it to help the healing.I have lots of dry blood now and time to time when it would drip would use the blanket to clean it gently.
I had some of the stitches out the other day and the nurse told me to leave the dried blood and try and not pick it at all. I haven`t touched my nose the whole time and thats what I was told. I think each person gets told different.
good luck xx
