Why I have cramps on my feet?

Cramps. Many chemical reasons, such as taking statin drugs, blood vessel problems, muscle disease, but these are all rare. Most of my patients' cramps are not from low potassium , magnesium or phosphorous or hypothyroid, but respond to stretching, extra potassium (very little) quinine, benadryl, (diphenhydramine) but they can have side effects, .
Reasons. Include dehydration , vitamin deficiencies, overworked intrinsic muscles, straining of an arch particularly if you have a high arch.
