Usually leg cramps come because of dehydration be sure to get 64 oz. Watera day. Also over exercising, under exercising or just standing in place for long periods. Are you taking a diuretic? If so you may need a different one, that spares you potassium. Don't increase you potassium without having a chem profile - or you could have other problems and discuss with your primary.. I rarely have leg cramps but they do happen at night after being on my feet all day or driving for several hours. I
recommend you make a hot pack (wet wash cloth in zip lock bag, microwave for 20 seconds, wrap in light towel ) and apply to cramp area.
I think this applies to lactic acid in our muscles.Runners also get those cramps, that's why you see them stretching Always works for me.
