Since I’ve been back from vacation, every time I’ve run I’ve gotten a side stitch and had to stop. Every time. Until this started, I don’t think I’d had one since elementary school. It’s high up on my right side and it hurts so badly I have to stop and walk. Anybody know why I’m getting them? Am I running wrong, breathing weirdly, pushing too hard, not pushing hard enough? Am I wearing the wrong shoes, the wrong sports bra, not enough sports bras? Please help, because this has been severely limiting my distance.
