Pretty much.
I have stretchs to stop the cramps in my shins, the rest of my legs muscles are, quite frankly, titanic.
Yeah, but what you often see is guys with humongous quads who'll develop all sorts of problems, because when running the power really should be coming from your hips, not your quads. You're likely to develop this when you're doing a lot of front squatting and not balancing it out with posterior chain exercises like deadlifts.
You might also have overdeveloped calves and a tibialis anterior that is not able to keep up with them, which is quite easy to fix, but I'm not a big believer of the idea. Anyways, a physical therapist who is good at his job should see your particular strength imbalance problem and if he didn't notice anything during the exam, it's likely that there's nothing to find. That said sometimes it can be a lot experimenting to correct your problem.
In any case it's a very shitty problem, man. Shin splints hurt like hell and generally they're hard to get rid off. Good luck and let's hope you're injury free again soon.
