It : It is interesting that you are that perceptive of your potassium being low; most patients are not. Classic symptoms of low potassium are weakness, cramping, or nausea. As you know, low potassium (hypokalemia) can be very serious and can cause problems with the heart rhythm in severe instances. Low potassium can be caused by low potassium intake in the diet, medications, and sometimes we don't know why patients have low potassium. If you think your potassium is low please have it checked medically.

Unusual: This is an unusual symptom from potassium deficiency. Leg cramps are seen, however. In your case the perpheral nerves seem to be affected rather than the muscles. If you're certain that the potassium is low when these symptoms occur, the treatment would be to take a potassium supplement. This wouldn't be dangerous unless you have kidney disease or take potassium retaining medications. Ask your MD
