My right foot keeps cramping up and curling. What could this be?
In general, cramping can be caused by many factors, including vitamin deficiencies. You may also have a muscle strain. Another reader here suggested it may be a Vitamin E deficiency. It's possible for your doctor to do a blood test that may help you determine if you're low in any particular vitamin or mineral.
In the meantime, try adjusting the things you can – for instance, drink more water and eat more foods high in potassium like dried apricots, bananas, potatoes, broccoli, spinach, and beans. A magnesium supplement may also be in order.
I have been suffering severe foot, ankle, shin and leg cramps at night that wake me up 3 to 4 times a night. I tried everything! Potassium, B complex ( 100 mg ), vitamin C and tonic water with quinine. Then I read an old vitamin book that I've had for 20 years and it said that It's really a severe vitamin E deficincy! I started taking about 2000 units of vitamin E in the morning a half hour before I ate and another dose with vitamin A at night. I still take the B vitamins and C. I've been cramp free for a long while now. It took about a week to build up in my body. It trully works, I wish I could tell everyone about this. Give the vitamins at least 2 weeks to build up in your system, you will be amazed! Also, heat ( like a heating pad or electric blanket ) works wonders too, with the vitamins. Good luck!
This is the most helpful explanation I have found online.
