foot and ankle

so if you dont have me on fb you did not hear the lastest new of what I did. I was helping the lady that lives across the street from my mom(know her my whole live), well while helping her trying to get her trailer hooked up I fell and twisted my foot/ankle. It got as big as an orange and is still some what big. If it does not go down by morning I  going to the er. I really hope I did not mess up my foot and ankle.  Ok I off kids are wanting to swim
