- Dehydration (make sure you are drinking plenty of water)
- Hormonal changes (cramps are more common in pregnancy and after menopause)
- Medication (ask your doctor to check if any medication you may be taking could be causing cramps, especially diuretics used for hypertension, asthma/emphysema medication, or osteoporosis medication)
- Lack of exercise (stretching several times a day and walking 20-30 minutes a day can really help)
- Degeneration in the discs or nerves in the low back (this would generally cause low back pain and nerve pain into the buttocks or legs as well)
- Low levels of potassium, calcium or magnesium in the blood stream (ask your doctor to make sure you are not deficient).
