What is Muscle cramp?
An involuntarily and forcibly contracted muscle that
does not relax
A muscle that involuntarily contracts is in a "spasm"
If the spasm is forceful and sustained, it becomes a
cramp
Muscle cramps cause a visible or palpable hardening
of the involved muscle

particularly the calf, are very common

muscle fatigue from sitting or lying for an extended
period in an awkward position can cause cramps

Rest cramps (Nocturnal
cramp)
often occur during the night
night cramps can be painful, disruptive of sleep,
and can recur frequently
such cramps are initiated by making a movement
that shortens the muscle
Example: pointing the toe down while lying in bed,
which shortens the calf muscle

Low blood calcium,
magnesium
Low blood levels of either calcium or magnesium
increase the excitability of both the nerve endings and
the muscles they stimulate
Commonly noted during pregnancy
Low potassium
although it is more common for low potassium to beassociated with muscle weakness

What is the treatment of skeletal muscle
cramps?
For many cramps of the feet and legs, stretching can
often be accomplished by standing up and walking
around

For calf muscle
cramp The person can stand 1 foot from
the wall
The feet should be few inches
apart
With arm slightly bent, placeboth palms against the wall
Slowly raise the toes of both feet
as high as is comfortable
Hold for several second, Then
lower the toes to the floor
Repeat 10 times

How can muscle cramps be prevented
Rest
cramps Can often be prevented by regular stretching
exercises, particularly if done before going to bed
Another important aspect of prevention of night
cramps is adequate calcium and magnesium
Calcium intake of at least 1 or 1.5 gram daily isreasonable
Supplemental magnesium may be very beneficial for
some

However, added magnesium can be very hazardous
for people who have difficulty eliminating magnesium,
as happens with kidney insufficiency
Magnesium is present in many foods such as:
greens, grains, meat and fish, bananas,
apricots, nuts, and soybeans

but a supplemental dose of 50-100 milligrams
of magnesium daily may be appropriate
