Cramps are usually a lack of hydration, but most people don't really sweat enough to dehydrate while hunting. This seems to be something different.
Where are the cramps? Calves, Quads, Hamstrings, Groin, Shins?
Seriously: You really should talk to a doctor.

(Unless you are walking a ton more than most people hunting.)
