I sprained my ankle and it is swelling on both sides and on top of my foot. Is it just a sprain or more?

I did it playing basketball last night. I came down on it wrong and knew it was hurt. I sat out for about 5 minutes and then decided to play more. I was able to play with a little discomfort. After the game I could walk on it with a limp. This morning I woke up and it hurt really bad-I can't even walk on it now. The swelling is on both sides of the ankle and on top of the foot. Is it just a sprain or possibly something more serious?

The only way to know for sure if it is not broken is to get x-rays of your foot. There are plenty of people who have broken one of their foot bones and still walk around on it. It could be just a hairline fracture or a bone could be out of place.
It probably wasn't the best idea to continue playing. You could have initially sprained it (which is an over-stretch of the ligaments), and then since it was weak from the sprain, you could have fractured it going back into the game. Either way, I would see a doctor so you can get a picture of your foot. They will take 3 x-rays from different angles to see all sides of all of the bones.
Either way, you will need to take it easy for at least 4-6 weeks.
