Should she see a doctor?

2 weeks ago my daughter(2 years) somehow injured her arm at the park. This was on 09/14. She complained of her wrist hurting and wouldn't use the arm or hand at all. She didnt cry continuously just when it was messed with and she would be fine after some ibuprofen.

Fast forward to today and she has been completely fine since 09/18. I completely forgot she had injured it over that weekend! I was holding her hand and her father held the other while crossing the street. I decided to give her a little swing and...

Boom. Wrist appears to be injured all over again. I feel so terrible! It doesnt seem to be nearly as bad as it was the first time however I'm not sure if it's something I should let heal on it's own again or take her to a doctor.

Any moms been in a situation like this before? What would you do?
