Quoting LawnMM
If it crept up after a workout or something its probably a sprain. If its a recurring long term soreness you might have tendonitis or something going. What exercises are you doing thats putting strain on your ankles?
I'd rotate your foot in circles both ways to stretch it out before lifting.
Well I generally don't think of it much even though it hasn't been a problem in years I had it for many years in school and never had anything happen. AFAIK I never sprained any joint or really ever harmed myself in anyway ankle or otherwise(was always putting the hurt on other people haha). Anyways, at work I generally do a lot of brisk walking, sometimes carrying ladders and stuff, standing around. I first noticed it after running the other day... so far I've been mostly doing the elliptical machine and some brisk walking on the treadmill and adding in some running here and there. But the other day I decided to go for gold and try running my heart out(not literally of course). The next day is when I felt it, and it's not bad but I think having to work 10 hours directly after that run and it was a harsh day I could barely stand I was so worn out.
I found this and am gonna give it a shot.
