Okay, I don't disagree with what anyone has said, but I would add that stretching can be helpful, especially after you walk or even during your walk. When I walk for exercise, I stop and stretch whenever I have hip or shin pain. If the pain stops after I stretch, I keep walking; if not, I head home. When I started working up my endurance, I couldn't walk more than 10 minutes or so before I needed to stop and stretch; after a few months of working on extending endurance I can make it for 30 minutes or so without needing a "stretch stop," and up to about 45 total. I'm also noticing greater flexibility, and I've been able to add short jogging intervals, which I really thought I'd never be able to do.
I would note that I've been maintaining my weight (because I'm struggling with eating, not exercise), so these improvements in mobility have happened as a result of steady exercise and gradual increasing of walking time, not because I'm any lighter than when I started.
I hope this pain is temporary for you.
