Low Mg: It is very important to keep all of your electrolytes in proper balance to prevent symptoms such as leg cramps and parasthesias. Make sure you take a daily supplement and eat plenty of veggies. Repeat labs to make sure all levels are back to normal after tx.

Possibly: Low magnesium can do all these things. Take an over-the-counter form of magnesium and see your doctor asap.

Possibly: The symptoms you have are frequently encountered in people with magnesium deficiency. Unless you have chronic kidney disease, taking magnesium as a trial to see if it helps, should be safe. Please discuss with your physician, but using magnesium glycinate or taurate, etc should avoid diarrhea that's more frequent with mg oxide and citrate forms. Gradually work up to 250-500 mg/day.

Foot and leg cramps: Low magnesium can cause cramps , as can deficiency in other minerals and nutrients. Try taking slow mg or other good source of magnesium along with extra calcium, potassium. Nightly foot and leg soaks with epson salts may help as well. Eat healthy diet with fruits and veggies.

Anything is possible: Low magnesium can happen with other electrolyte abnormalities, low ca, low k+. These are usually related with conditions such as kidney stones, heart failure, arrythmias, strokes, and bronchial asthma. Your symptoms may be related if there is any likelihood of strokes in your personal or family history. Suggest you check with your pcp.
