In Canada (at least Yukon and Ontario) there is a (free of course) phone number where you can chat with a nurse any time you want. They generally tell you what you can do or whether you should go to the emergency room. It's super handy for people that live outside of cities where it is a long drive or possible even a plane trip to the nearest doctor.
Implementing a smartphone application where instead of just consulting WebMD, it actually connects you to a nurse would be the best route to take with this. It would be similar to a phone call, but you could include photographs, or even audio recordings of how you scream when you touch the bubon on your leg.
