Cramping - always the same muscles

Right now I’m nursing a pain in my vastus medialus, about six inches up from the knee, under the sartorius muscle and that comes on with over-unders. Adductor longus and gracilis in both legs are the ones that hurt more than anything else on aerobic/tempo workouts.

It’s not a cramp, they simply burn more than the rest. Should I be concerned?
