one thing u can do to ease his stress while you are cleaning the wound for example is to put a sock over his head, preferably clean though lol. This helps to calm them down and also gives ou security when working with your bp. With the oral meds you just have to get on and do it. The best thing to do is to just do it quickly and efficiently. With his viv etc, keep it simple, paper preferably white paper so u can keep an eye on whats coming out of the snake, be it back end or the wound. Just give a coupel of hides, a small water bowl which is big enough to drink from and not too soak, to help the wound healing we need to keep it fairly dry and clean. Without pics its hard to say anymore. You will find that your BP will shed more regularly due to the wound, and usually afer a coupel of sheds you will hardly know the wound was there.
Best of luck and major Kudos to you in helping out!!!
