@Rico: It's possible that you sustained a more serious injury than initially thought. It's important to seek medical attention, even if it means seeing the only doctor on the island. Your health and well-being should be the top priority. Stereotypes have no place in this situation.

I rest my case.
@NotGuiltyThisTime: Have you tried icing it and taking pain medication? It's possible that there could be a fracture or other injury that requires medical attention beyond just waiting for it to heal.
