I have done it all too my ankles. A "sprain" is anything from a stretch of the ligament to a tear. My last one was a complete tear of my lateral ligament. I waited 3 month before seeing a doctor, & than was asked where my ligament went, it had completely dissapeared over time of not getting it taken care of. If I went right away, it might have been able to be saved. If you are in serious pain to the point of not being able to bare weight, than get an MRI ASAP. Physical therapy saved my ass. If its just a mild sprain, than ice & elevate as often as you can take, & do ankle raise on a step. You need to strengthen the muscles around the ankle to avoid it again. I feel once you do it, you are suceptable to it again.
