Arm Twitching Is Normally Not Serious

We all experience muscle twitching form time to time, with arm twitching and leg twitching being the most common types encountered. Twitching can also occur in the face, particularly the jaw or the eyelids, and even on the abdomen. Twitching in the limbs is the most commonly experienced however. A twitch can be thought of as a mild form of a muscle spasm. A spasm, such as a cramp, is usually much more violent and often very painful. Twitching is generally not accompanied by pain, or at least severe pain, but can nevertheless be a nuisance.

There are a number of things that can cause arm twitching, or twitching elsewhere on the body for that matter. More often than not, the twitching is not anything to be concerned about. In other words, it's a muscle responding to some condition, which in the overall scheme of things, isn't anything serious. If arm twitching is becoming frequent, or if the twitches are increasing in intensity, and there are other disorders as well, such as muscle tiredness or weakness, it would be a good idea to consult with a neurologist, in the unlikely event that there is a nervous system or neurological disorder, such a  muscular dystrophy or muscular atrophy. Twitching alone is usually not a symptom of such a severe disorder, as it would normally be accompanied by other symptoms as well. Still, for peace of mind and possibly to gain some relief from excessive twitching, a visit to a care provider shouldn't be ruled out.

Been Doing Bench Presses? - Much of the time however, arm twitching can be traced back to something, whether it be something eaten, or an activity which stressed the muscles. A common cause of arm twitching is physical exertion, with weightlifting topping the list. When the biceps and/or triceps are subjected to great stress, such as during a bench press or during pull ups, arm twitching can be a delayed reaction to the muscles having become greatly stressed or fatigued. A person who has bicycled a great distance or run a great distance will often experience twitching later on, usually in the legs. An accumulation of lactic acid in the muscles is thought to be a cause of muscle twitching following exercise or other forms of exertion.

When Too Much Or Too Little Can Be A Cause - Too much of a substance, such as caffeine, some medications, or certain deficiencies can be behind a case of arm twitching. A second cup of coffee isn't likely to initiate an outbreak of twitching, but if one is on a given medication, and at the same time is suffering from a deficiency in a vitamin or mineral, the combination could certainly initiate a reaction in the muscles, arm twitching being but one example. A deficiency of either calcium, magnesium, or both, can lead to a case of muscle twitching, as can a deficiency in vitamin B6 or vitamin B12.

Medications thought to be a cause include several prescription antibiotics. This suggests that those suffering from minor bouts of arm twitching might take a look at their dietary habits, and medications, as well as possibly looking into their exercise routine to see if changes might be in order.

Summary – Seldom Anything Serious - For the most part though, arm twitching is simply a muscle's response to being fatigued, and nothing more. As one person put it, “Arm twitching is like stomach gas. If it's only an occasional occurrence, it doesn't mean anything". To put it another way, arm twitching is no more an indication of the presence of muscular dystrophy, than stomach gas indicates the presence of stomach cancer.
