what causes muscle spasms

Have you been noticing that you have been having muscle spasms more often lately? With so many types of pain, most people experience occasional muscle spasms. But if the condition starts to restrict your life then you may need to find out the underlying cause and how to get it treated.

Muscle spasms tend to be involuntary, and you’ll usually notice them in one muscle at a time. The intensity level varies in intensity from subtle twitches to powerful, painful spasms.

What causes muscle spasms and how can you find relief? Read on to find out everything you need to know about muscle spasms and how to get relief.


Dehydration is one of the most common causes of muscle spasms. When your body doesn’t have enough fluids, it can lead to cramping, electrolyte imbalance, or low blood pressure. Many things can cause dehydration, including sweating, vomiting, and diarrhea.

If you’re dehydrated, you may experience muscle cramps, spasms, or weakness. To prevent dehydration, drink plenty of fluids, especially during hot weather or when you’re participating in strenuous activity. 


There are many potential causes of muscle spasms, but the most common cause is overuse. When a muscle is used excessively, it can become fatigued and start to spasm. This is often seen in athletes who train too hard or do not allow their muscles to recover properly. 

Muscle Fatigue

Muscle fatigue occurs when the muscle is unable to generate the force necessary to contract properly. This can be due to overuse, as in repetitive motions, or to prolonged contraction, as in isometric exercises.

Fatigue can also be caused by electrolyte imbalance, dehydration, or inadequate blood supply to the muscle. They usually resolve on their own with rest but may need medical treatment if they are severe or persistent.

Nerve Irritation

Nerve irritation can be caused by a variety of factors, including injury, inflammation, or compression of the nerves. This can lead to the nerves sending signals to the muscles that cause them to contract involuntarily. 

If the cause is nerve irritation, treatment may include rest, ice, and anti-inflammatory medication. In more serious cases, treatment may require medication or physical therapy so be sure to consult a nerve pain doctor immediately.

Muscle Strain

Muscle strain is a common cause of muscle spasms. When a muscle is strained, it is stretched or torn. This can happen due to overuse, trauma, or repetitive motion.

This can cause inflammation and pain, as well as muscle spasms that are characteristic of a muscle strain. Muscle strains can usually be treated at home with rest, ice, and over-the-counter pain medications. More severe strains may require physical therapy or even surgery.

Low Levels of Minerals

Minerals are essential for muscle function, and when they are low, they can lead to cramping and spasms. When the body is deficient in minerals like magnesium, calcium, and potassium, it can cause the muscles to seize up and spasm.

This can be due to a diet that is lacking in these essential nutrients, or it can be due to certain medical conditions that cause the body to lose minerals more rapidly.
