I was swimming today and i feel like i made an awkward move with my elbow and it's hurts a lot not but it's not swollen what should i do ?

Rest: Consider the use of an over the counter NSAID such as advil, (ibuprofen) alleve, or Ibuprofen as well as rest, ice and avoidance of painful use. If not better in a week or so then see an orthopedist.

Swollen elbow: Apply some ice (with a towel covering the ice) for 15 minutes at a time. Take ibuprofen, put it in a sling if you can get one, and rest it if not. See a doctor if it still isn't better in 2 days or you have any new concerning symptoms.
