The morning of the op prob be careful to use anything too strong, they dont like anything sitting on the skin like mousturiser, maybe something like simple, thats got no perfume or anything in it. I would stay away from anything on the wound, even getting water in it can get infection in early days, my mum says she sees people all the time who just get in bath with stitches and think cos it’s just water that it’s ok but once it’s damp it could get infected, nurse said I can get steri strips wet now but my mums banned me until the wound closes! So shallow baths for me still just to be on the safe side lol!
