my DH is always doing that but with a stanley knife I don't muck around I take him straight to er I rang them one day to say he was coming in and they said don't come before 5PM as the Dr won't be there to stitch it and I replied there is nothing left to stitch, he had cut of the whole side of his finger from the tip to the first joint, when we got there she said I see waht you mean. he is so well known in er it isn't funny anymore. he did heal ok after months of going to the dressing clinics. now when they treat him they give me the bandages and so forth and I treat him at home after the first couple of visits, I could probably get a job at the dressing clinic DH thinks I do a better job of bandaging than they do, I guess practice makes perfect and I have had lots of that. he took me in one day and they all had a shock cause it was me not him
