Muscle twitching represents fine movement of a small number of muscle fibers. These parts of a muscle contract involuntarily and uncontrollably. Muscle twitching is medically known as fasciculation and if it lasts for a long period of time, it can become annoying and interfere with one's performance.

Muscle twitching is a sign of many medical conditions such as dietary deficiencies, drug overdose and it also occurs as a side effect of certain medications. It is considered to be a normal reaction after exercising. Muscle twitching may affect each and every muscle in the body and is generally intermittent.

Uncontrollable Contraction of Muscles

In the majority of people muscle twitching is a temporary problem and withdraws spontaneously. This is why its occurrence does not have to be alarming.

Most of the time muscle twitching develops as a consequence of anxiety. Anxiety is actually considered to be the leading cause of muscle twitching. If a person is exposed to stress and situations that increase anxiety, he/she is at higher risk of developing muscle twitching. The problem can be easily dealt with by highly effective relaxation techniques as well as yoga or meditation.

Apart from anxiety, muscle twitching occurs due to exercising. In this case the problem is connected with intense workout such as weightlifting. People who want to build muscles in short period of time perform strenuous exercises and may end up with muscle twitching. Another cause of such twitching is a rigorous chest routine and the problem may also occur if one is engaged in strenuous aerobic exercises. Muscle twitching caused by exercising can be dealt with by resting and modification of the exercise program.

Furthermore, intake of certain substances may induce muscle twitching. This particularly refers to caffeine. Caffeine is found in many drinks and food products (coffee, tea, cola etc.). Being moderate in consuming such products may help in reduction and elimination of muscle twitching.

In some people muscle twitching is associated with a deficiency of certain minerals and vitamins (calcium, magnesium, vitamin B6, B12 etc.) If this is the case, mineral supplements bring the problem under control.

In case muscle twitching develops as a side effect of medications, the particular drug is replaced with a suitable substitute.

And finally, if muscle twitching develops as a sign or complication of some chronic illnesses (Lyme disease, myasthenia gravis, fibromyalgia etc.), it may be controlled with medications prescribed for the primary illness.Weakness in ArmA lot of people suffer from arm pain and accompanying arm weakness.
