Middle Back Spasms Causes- Definitions and Causes of back spasms mid back.

Middle Back Spasms causes and Back spasms in mid back - Definition, Symptoms and Its Causes

There are a great number of people suffering from mid back spasms which can be defined medically as the fast and involuntary contraction of the muscles located in the back area. This can lead to pain that can last for minutes that will slowly fade. Although this condition may not be detrimental to health, back spasms can be associated with other underlying conditions like muscular and at worst neurological disorders. With these, it is best to understand this condition as well as the many known causes of muscle spasms.


Understanding Cramps or Spasms

In order to acquire the best knowledge about middle back spasms it is most helpful to gain the exact knowledge about the term “spasm” or cramp. Essentially, these terms are used to describe the abnormal activity of the muscles that causes an abrupt painful contraction.

In most cases, back spasms are accompanied by muscle stiffness even at a relaxed state, very slow relaxation of muscles. This also includes fasciculation which is a term used to refer to the spur of the moment contraction of muscles that are in the relaxed state.

Fasciculation is very evident in middle back spasms and is characterized by painless muscle cramps that are accompanied by fast and uncoordinated spasms of the tiny muscle fibers. Hence, patients must be able to describe accurately the symptoms that they are experiencing for accurate medical diagnosis.


What Causes Abnormal Contraction?

The abnormal contraction experienced in muscle spasms is actually attributed to the abnormal central nervous activity. Basically, the mechanisms in the central nervous system most particularly in the brain aid in regulating muscle contraction. When these mechanisms are distorted, spasms happen and this causes the motor neurons that are responsible for movement to become overly sensitive.

In cases of middle back spasms, the muscle membrane can be too sensitive, leading to muscle contraction without even a stimulus. In these instances, the calcium ions may not recover fast enough which results to lengthened contractions.

Hence, distorted brain mechanisms and receptive motor neurons caused by nerve damage may result to these spasms. Some of the conditions related to this include:

What Are The Other Causes?

Apart from the conditions mentioned above, there are still a lot of conditions that can be associated with muscle back spasms. So, it is best to know the possible causes of muscle spasms which are the following:

  • Strenuous activities- Over-exercising can lead to spasms due to the fact the muscle relaxation requires energy which is used to regain the calcium that functions to unlink myosin and actin. If a person exercises or performs strenuous activities for extended periods, neglecting fatigue and pain sensations, then it can lead to extreme loss of energy. Thus, the muscles will also lose its ability to relax, resulting to middle back spasms.


  • Electrolyte imbalance and dehydration- In essence, loss of essential electrolytes such as potassium, sodium and calcium due to conditions like vomiting, diarrhea and profuse exercise can distort the normal levels of fluids and electrolytes in the nerves and muscles. When this happens, the muscles will have a tough time to recover which then leads to spasms.


  • Inflamed organs- Inflammation of the gallbladder which may be due to gall stones can also be another cause of middle back cramps. This condition will cause pain from the middle back that may radiate to the right side upwards. Hence, untreated gall bladder problems should be treated as soon as possible to avoid further damage.

These are the basic truths that you need to know about middle back spasms so as soon as symptoms are felt it is always best to consult a doctor for appropriate recommendation or medical treatment.
