How do I know if my elbow pain is serious?

Most cases of elbow pain (which are often results of sprains/strains) subside naturally after a period of 2 days to 2 weeks. However, if the pain gets worse or persists after the 2-week mark, seek immediate medical attention. Sometimes, elbow pain is merely a symptom of a more serious or underlying condition, so pay attention to other symptoms that accompany the pain.
