Possible causes of cramps in the feet include poor blood circulation in the legs, muscle fatigue, nutrient deficiency and not enough stretching before exercise, according to WebMD. Muscle cramps are also a side effect of certain drugs and medications, such as Lasix, Aricept and Evista.
Other causes include dehydration, exercising in the heat and overexertion. Malfunctioning nerves caused by spinal injuries or a pinched nerve in the neck or back may also result in muscle cramps. Gentle massage, stretching, icing or warming the muscle and Epsom salt baths may help remedy muscle cramps. Eating more foods that are rich in magnesium, calcium and vitamins helps to prevent muscle spasms. Other preventive tips are to stay hydrated and stretch before exercising, says WebMD.
For the most part, self-care is enough for muscle cramps as they go away in minutes. If a person experiences muscle cramps frequently or for no obvious reason, WebMD recommends talking to a doctor. While most muscle cramps are benign, some may be symptoms of underlying issues, says Mayo Clinic. Certain factors, such as age, pregnancy and other medical conditions, result in a higher risk for muscle cramps.
