My scar hasn't been treated for a couple of days, so I've had to clean it up this morning ... and you know I have Healing elements on my shawls. It helps me to wear them, it's the only thing that does, so it has to stay on for a bit. In any case, my scar absolutely stinks when it gets to this state ... so trust me, honey, it's better this way. You'll just have to accept that there will be times when I have to wear my wrappings, that's just how it is.
