Playing tennis today, going for a ball then changed direction too quickly... felt the ankle collapse, heard it pop and ended up lying on my back. I think it's lightly sprained I iced it immediately at the court, came home sprayed some DMSO on the entire ankle/foot, iced it again then elevated the foot. Took some Ibuprofen and a Tylenol to quell the throbbing. Right now, it's feeling pretty good... although it feels slightly weak and pops a bit when walking or placing weight on it. I think I iced it in time, as the swelling is minimal. I'll ice it throughout the day and then wrap the ankle in a compression bandage, later this evening. Any other advice?
