If the nurse was even a tiny bit concerned you would have been given info about who to contact if you have any concerns during the weekend. I thought that slough is part of the body's healing process & the antibiotics must have started to work. Please don't give that arrogant little man the luxury of your thoughts, revenge is defo a dish best served cold & being officially criticised will start that ball rolling. I hope you have a restful weekend, however, I hope his will be totally vile -food poisoning, piles, wasp stings & then his wife/husband/partner leaving him, clearing out the accounts & taking the dog.
