question: I have been diagnosed with hypokalemia I take potassium substitute but for the last 4 day have been cramping in the legs and hands and feeling like crap, cant understand, I feel cramp in the chest at times. I have been working long hour and may not have been eating properly, my worst count was 2.7 8 weeks ago. do you think I should get it checked again even if I am taking the k sub? worried I dont feel well.
