If you were able to walk on it with a bearable pain, it's not a terrible sprain, probably average. If the pain was far too much to walk, you done fucked up. I rolled my ankle in March, tore two ligaments completely apart, and there is still pain with certain motions. After a month in a boot, a month of physical therapy, and a couple months of minimal skating. I'm still nowhere near happy with how I'm skating, I don't think I'll be able to skate the same again. You need to give it as much time as you can to heal, ankle ligaments are some of the most fucked parts of our body, and it takes forever to heal. I'm assuming since they thought it was broken, you have a bad sprain, so you probably have a long time before it'll feel close to 100%. I'd say nay on the skate trip. but you can risk it if you want.
