Ali,
I am so glad you were able to get on and post. Now that you have, rest your arm. The more you use it, the more swollen it will be. I am so sorry this happened to you. I agree with Karen, never second guess how bad a fall can be and get it xrayed. I'm glad you're getting prompt treatment and that they were kind to you. Give your Mum a hug for us. She obviously loves you very much to be willing to keep in touch with us on your behalf!!! Take care, honey!!!
