This is a good time of year for a break anyhow. Give it 3-4 weeks of complete rest. After that, slowly work on coming back up to speed. If the pain persists, then push for a sports ortho.
Elbow pain basically can come from overuse (even with good mechanics), mechanics that place undue stress on the elbow, or a traumatic injury. Figuring out which was the likely cause can help prevent recurrence. Good luck.
