Normal post-run soreness is a burning or aching feeling in the muscles you just worked, along with general tightness that shows up 24 to 48 hours after a run and settles within a day or two. That soreness comes from microtears in the muscle as it rebuilds, and it typically eases once you get moving through your day.
Running pain that needs attention looks different: sharp or unbearable pain, soreness that is present even at rest, or pain that shows up at the start and end of a run and gets worse with exercise or stretching. Medical & Sports Massage treats that distinction as the starting point for any conversation with a runner, since pushing through real pain can turn a small issue into a larger one.
