If so, have you found anything that helps relieve the pain? Taking over the counter medication is a common way of dealing with nighttime leg cramps; unfortunately, you will continue to toss and turn in your bed for 30-45 minutes as you wait for the medication to take effect. While all along you more that likely have one of the best leg cramp remedies sitting in your kitchen: MUSTARD!!!

Causes of Cramping

Nighttime leg cramps can have a variety of causes. The most common being a shortage of minerals, such as calcium and magnesium in your body. A shortage of acetic acid can also cause cramps. The body uses acetic acid to produce acetylcholine, which is essential for leg muscle contractions. This is why mustard is effective for leg cramp relief. Mustard contains acetic acid.

Daily Prevention

Yellow Mustard is the only kind of mustard documented to relieve nighttime leg cramps. When nighttime leg cramps occur, take a teaspoon or two of yellow mustard. The mustard should take effect almost immediately, allowing you to easily get to sleep. The immediate relief is believed to be turmeric, which is used to give mustard its yellow color. Turmeric has many anti-inflammatory properties which are believed to be the cause of immediate relief. If you find yourself to be taking mustard on a regular basis to relieve nighttime leg cramping please consult your doctor. Constant leg cramping could be an indicator of a more serious medical problem. Your body needs 5,000 IU(international units) of vitamin D with a good multi-mineral daily to help prevent nighttime leg cramps.

I am so glad you asked this question, just the other night this happened to me, the muscles in the back of my thighs was so cramped that the pain woke me up, and when i tried to walk it off my legs would not move right. It's a scary thing when your half asleep. My first thought was it was MS but after thinking about it the following day i realized that i was most likley dehydrated a little from the day before due to being outside in the heat and not drinking much water.

Drink plenty of fluids & try to exersise daily.....prayers sent.)
