I sprained my ankle yesterday, there was a discreet pothole in the street and I tripped into it. Immediately I felt pain through my ankle and noticed it began to swell. I was able to walk with a limp after that until I got home. I kept walking on it trying to keep the movement but later on I realized that walking in it was probably stressing it more and it began to swell even more. I stopped walking on it after that and kept ice on it, relaxed and kept it elevated. I took ibuprofen as well for the pain and slept on it. I woke up in the morning with my hands feeling a hot and a bit swollen. Later on I noticed that I developed a fever and took some Motrin. I was wondering what would cause a fever for a sprained ankle. Maybe I tore a ligament or perhaps have a hairline fracture. I m able to move my toes and my foot from side to side but the swelling is still very much there. I will be going to the doctor tomorrow but I wanted an opinion ahead of time out of curiousity.
