Dogs lower front paw is swollen?

A week ago my dog fell down the stairs(3-4 of them). He yelped and began limping on his front right paw. The area located between his toes and his duclaw(forefoot they call it) is swollen. I took him to the vet the next day, I was on vacation so it was not my regular vet. They took xrays and said they didnt see any significant break. They also told me they were not sure what was causing the swelling, it could be a sprain, ligament tear or tendon...no I was not pleased with this vet. They prescribed meloxin which the vet said was a pain reliever...I asked if he needed to be on an anti inflammatory and she said that pill was both. She also put him in a ridiculous splint, that I had to take off him because he was slipping and sliding all over the place with it on. The splint went from his toe all the way up to his armpit...it was causing him pain. I returned this evening from vacation and have an appointment with my vet tomorrow afternoon. I was wondering if anyone else has gone through something similiar so I can be prepared when I see the vet tomorrow. My dog can put very little weight on his front paw, it has been swollen for a week and seems to handle the pain well.
