Μυϊκές κράμπες
Οι μυϊκές κράμπες εκδηλώνονται ξαφνικά, με αθέλητες συσπάσεις των μυών, μετά από σωματική εξάσκηση ή κατά τη νύκτα, διαρκούν από μερικά δευτερόλεπτα έως μερικά λεπτά και προκαλούν πολύ δυνατό πόνο.
Οι κράμπες εκδηλώνονται συχνότερα στους μυς του πίσω μέρους της κνήμης (γαστροκνημιαίοι μυς), στους μυς του εμπρόσθιου μέρους των μηρών (τετρακέφαλοι) και στους μυς του πίσω μέρους των μηρών (μηριαίοι δικέφαλοι μυς). Επίσης, είναι συχνές οι κράμπες στα πόδια, χέρια, στα μπράτσα, στην κοιλιά και στο θώρακα.
Στις πλείστες περιπτώσεις, οι κράμπες δεν συσχετίζονται με προβλήματα υγείας. Ωστόσο κάποτε η κατάσταση είναι διαφορετική.
- Δυσλειτουργία νεύρων, όπως στις βλάβες του νωτιαίου μυελού και στη συμπίεση ρίζας νεύρου, που προέρχεται από το νωτιαίο μυελό και εξέρχεται από τη σπονδυλική στήλη
- Η υπερβολική καταπόνηση μυών
- Η αφυδάτωση
- Η έλλειψη ορισμένων στοιχείων όπως το ασβέστιο, το μαγνήσιο και το κάλιο, εξαιτίας διατροφικών διαταραχών ή λόγω απώλειας των εν λόγω στοιχείων από τους νεφρούς
- Η ανεπαρκής τροφοδότηση των μυών με αίμα
- Η γήρανση, που κάνει τους ηλικιωμένους να είναι πιο επιρρεπείς στο να παθαίνουν κράμπες.
Muscle Cramps vs. Muscle Spasms
There are three types of muscles in the
body. Cardiac muscle makes up the heart. Smooth muscle cells line the
blood vessels, gastrointestinal tract, and certain organs. Skeletal
muscles attach to the bones and are used for voluntarily movements of
the body. Muscle spasms occur when a skeletal muscle contracts and does
not relax. Muscle spasms are forceful and involuntary. A sustained
muscle spasm is called a muscle cramp. Leg muscles, especially the
quadriceps (thigh), hamstrings (back of thigh), and gastrocnemius
(calves), are most likely to cramp, but any skeletal muscle in the body
can cramp. A “charley horse” is another name for a muscle cramp.
What Causes Muscle Cramps?
There are many potential causes of muscle
cramps including physical exertion in hot weather, overexertion,
dehydration, electrolyte imbalance, and physical deconditioning. Many
times muscle cramps are not cause for alarm; however, at other times
muscle cramps may indicate a more serious underlying problem such as
liver cirrhosis, atherosclerosis, ALS, thyroid disorders, or a problem
or issue with the spine or spinal nerves. Certain medications and
supplements may be associated with muscle cramps.
Signs and Symptoms of Muscle Cramps
Muscle cramps can range from being a mild
nuisance to incapacitating and extremely painful. The cramped muscle may
be visibly distorted or look knotted. Twitching may be evident. The
area of a muscle cramp may be firm to the touch. Some muscle cramps last
just a few seconds, while others can last 15 minutes or more.
Medications That Cause Muscle Cramps
High blood pressure medications, insulin,
birth control pills, cholesterol-lowering medications, and certain types
of asthma medications (beta-agonists) may cause muscle cramps. These
medications cause cramps by a variety of mechanisms. They may interfere
with electrolyte levels, contribute to the breakdown of muscle tissue,
or interfere with blood flow. Report medication-related muscle cramps to
your doctor.
Muscle Cramps at Night
Muscle cramps at night, especially in the
calves, are very common and affect up to 60% of adults. Women are more
likely to suffer from nocturnal leg cramps than men. They are also more
common with age and contribute to insomnia. Muscle fatigue and nerve
dysfunction are believed to be contribute to nocturnal leg cramps.
Management of nocturnal leg cramps may include stretching, massage, and
treatment of any underlying disorders that contribute to the condition.
Muscle Cramps during Pregnancy
Many pregnant women experience muscle
cramps, especially in the legs and at night, during pregnancy. The
levels of fluids and electrolytes in the body fluctuate during
pregnancy, which may contribute to leg cramps. Increased pressure on
pelvic nerves may also play a role.
Muscle Cramp Remedies and Treatment
The vast majority of leg cramps resolve on
their own within a few minutes without treatment. As soon as a muscle
cramp comes on, stop doing the activity that precipitated it. Stretching
and massaging the area may help relieve muscle cramps. Apply heat to
help relax a cramped muscle. A cold pack and nonsteroidal
anti-inflammatory drugs (NSAIDs) help relieve pain. Always consult a
doctor if muscle cramps are severe or if they recur frequently.
Medications to Treat Muscle Cramps
Pain medications, muscle relaxants, and
anticonvulsants may be used to treat muscle cramps. It’s best to use
lifestyle interventions like hydration, stretching, and the application
of heat and cold to treat muscle cramps, but medication may be helpful
when other strategies are ineffective.
Muscle Symptoms and Anxiety
Generalized anxiety disorder (GAD) may
include symptoms like muscle aches, muscle tension, and twitching.
Anxiety is often accompanied by other body symptoms such as fatigue,
sweating, nausea, and shortness of breath.
Muscle Cramp Prevention
Strategies for reducing the risk of muscle
cramps include varying exercise routines, staying well hydrated, and
stretching. Warm up by jogging or walking at a brisk pace before
stretching the calves, hamstrings, and quads. Maintaining good levels of
electrolytes will help, too. Sodium and potassium are lost during
exercise, especially in the heat and with excessive sweating. Sports
drinks can help replenish sodium and potassium.
