I kept my cutting to one arm, trying to be conscious of stuff like this. when I go for blood draws and such I always insist on using my unscarred arm. there have been times they have insisted on using my other arm and asked what happened. I don't make up stories since I know they will know and don't want them thinking I am a liar. I just say...life hasn't always been so good....I have thought of tattoos as well but then that would cover up my whole forearm and I just don't like such obvious tattoos. but maybe it is something to think about, at least for the biggest of the scars.
