Question: M: Dr. Cardano, I woke up in the middle of the night with a terrible pain in my right foot. W: Did you cut yourself or knock it against something? M: No. It just started hurting all of a sudden. W: Can you describe the pain for me? Is it a sharp pain that comes and goes? Or is it a constant, dull pain that doesn't really ever go away? M: I suppose it's more like the first one. But it's definitely difficult to walk, so it's not really going away, either. W: Let me see those feet, Bobby. M: Do you want me to take off both socks? W: Yes, I'd like to compare your right and left foot. Ah, the right foot is pretty red, and it looks bigger than the left one. It also feels warmer. M: What does it mean, doctor? W: Well, I don't know for sure. It could be one of a couple of things. I'm going to send you up to the lab to get some blood tests. Check in to the lab on the third floor. I'm sending them some instructions. Come back down here as soon as it's finished. M: OK. I need to use the restroom first. Can you tell me where that is? W: Go downstairs to the first floor. It's right next to the elevators. M: Thanks. What was said before this conversation?
Answer:
W: So, what seems to be the problem, Bobby?
