Causes of foot cramps

Yes. My wife is quite conscious of fruits and vegetables she needs to be eating. She is a water camel when it comes to consuming water.

Does she wear heels during the day? Have her try standing toe raises in sets of 25 and then in a seated position with legs straight out in front of her, flex and point her toes in sets of 25. A follow up soak and rub with lotion will help too.

I stretch her out ever night and she does some specific stretches for her feet on her own. She does not wear heels.

A banana a day keeps the foot cramps away.

@GeorgeGee They do not. My wife eats them fairly regularly and still get them.

Try diet tonic water ( with Quinine). The quinine will help stop the cramps, just don’t drink too much. The active ingredient in several OTC remedies for cramps is quinine.

The nightly cramps on legs is a sign of the lack of magnesium of the body. As @MissAnthrope said it too. No remedy, only magnesium or multivitamin pills can help.
