Hello there
Well there are multiple reasons for cramps in the calf.
Sometimes certain sterneous activity may strain the calf...or some time more serious thrombosis problem may be there.
Is your calf painful to touch for even if low preassure is put by fingers?
Has your calf become shiny and swollen?
Do reply back with answers as these are important signs.
