Yep. I got them so bad that my muscles in my calves felt twisted for weeks. I was told the same thing, that prednisone depletes potassium. My doctor checked my potassium level, and it was normal. I was then told, by someone else, that the prednisone could have messed up the balance of my electrolytes. Electrolytes include sodium, calcium, magnesium, and a few other things in addition to potassium.
