I'm 36 and haven't played soccer regularly in the last nine years. In the last two months, however, I've been playing about four times a week. It's fun and it keeps me in better shape than just about anything I've done. I'm recovering the skills that I used to have, and I feel pretty good about the way I play. The only problem is that I've been experiencing a bit of soreness in my legs. Once I start playing, however, I don't even think about the soreness, and the soreness doesn't affect my game. It's only when I'm resting at home or taking leisurely walks that I feel the soreness. Will this soreness eventually go away or is it just the kind of soreness I would get at my age? It's not really much of a problem, but I'd like to hear your thoughts on it.
