Dr. Oz does not answer questions on the internet or on this site.
But I can answer your question.
There are 3 main areas
Bad circulation...pulses in the legs have to be checked, and sometimes a study called doppler studies of the legs [arterial] are needed.
Problems in the lower spine, such as spinal stenosis and other problems such as disc disease of the lower spine.
magnesium calcium potassium sodium and chloride all need to be checked.
Sometimes cramping can also be more prevalent in diabetes, thyroid
and neurological disease as well.
Let me know if you have further questions, details or need clarification, just use reply.......
