What does it look like? You might have an abscess from the miss... I have done this before, and it sucks. What usually happens whenever I do miss a shot of bupe, which is rarely, is I start out pushing the plunger after registering and sometimes puncture through the vein from pushing to hard, then I feel it start to burn when this happens. So I pull out a hit another vein instead, this usually happens to me when trying a newer, softer vein than one of the ones I normally hit.
Did you pull out when you felt it start to burn or just bang the whole shot anyways and keep going? If so its very possible you could have an abscess. If it is an abscess it will usually be very swelled up and red, and you should seek medical attention from the ER or an urgent care clinic, not your sub doc, then you most likely will lose your script if you go to your sub doc and tell them. If it gets worse or keeps hurting definitely seek medical attention. If its just a slight miss, and not an abscess, just apply a cloth with hot water to it and not use that vein anymore, there is no need to keep hitting the same spot over and over when you IV, that will lead to serious problems eventually if you don't rotate sites when you IV.
