Dear Doctor, I have a wound on my right hand ( as show on the picture ) which isn't healing since 3 weeks, I have tried handyplast, healing skin cream, no matter I have to use hands to do things like cooking, cleaning...with or without soap and sanitizer (sometimes). How can this cut would heal ? (Also on the same finger I was using feviquix... which dried and came off with skin later when I had a cut from a kitchen knife ( tetvacc taken 6 months ago).)
