Continued calf pain

There are multiple possibilities depending on the location in the calf - is it near the achilles, in the gastroc head, closer to behind the knee, what kind of streching do you do, do you notice it worse after speed work or hills, are you a pronator, how tight is the ITB, do you roll your calf muscles on foam roller, etc?

I recommed you get an eval by a sports oriented PT. I am a heavier guy and freq have had calf issues - they unkink it very quickly and often all you do is modify the running you do not usually have to stop it altogether. Good Luck!

By "tight", do you mean a precursor to a cramp? Does it cramp if you go harder? Most cramps are the result of overwork; less often from hydration issues. Static stretching won't help these issues and could make it worse - depending on which expert you believe. Have you ramped up your training volume recently?
