Like I just said, speedwork is tough.
Right now, my right thigh is hurting like I overused it; thankfully, it feels only like a muscle issue, which heals with the proper doses of rest, massage, and occasionally anti-inflammatory type drugs.
But the best thing I've found to keep this from happening is the first cousin to the ice bath- the cold shower. Aimed directly at the right place for a long enough time, it really keeps inflammation from becoming a problem, even hours after the workout.
Not days, though. Not doing it after speedwork on Tuesday was a mistake; enjoying a long, hot shower compounded the issue.
*sigh* after all I've been though, you'd like I'd have learned by now, ya'know? :P
