Why do I get random spasms in my arm?

Twitches and spasms can be warning signs that this common condition is affecting the nerves that control your muscles. Some people are born with it, but it can happen because of an injury, infection, disease, alcoholism, and some medications. Diabetes is the leading cause of neuropathy.

What diseases cause involuntary muscle spasms?

Nervous system conditions that can cause muscle twitching include:

  • Amyotrophic lateral sclerosis (ALS), also sometimes called Lou Gehrig disease or motor neurone disease.
  • Neuropathy or damage to the nerve that leads to a muscle.
  • Spinal muscular atrophy.
  • Weak muscles (myopathy)

Why am I getting muscle spasms for no reason?

Overexercising, dehydration, and stress are the most common causes. The spasms happen when the muscle suddenly moves involuntarily. Muscle spasms may feel like a slight twitch or a painful cramp, and they can occur in the muscles in any part of the body.

What causes involuntary jerking of limbs?

A disturbance to the central nervous system (brain and spinal cord) most likely causes these involuntary muscle twitches. For unknown reasons, the central nervous system sends an electrical impulse to muscles. Rarely, myoclonus occurs after an injury to the peripheral nerves outside the central nervous system.

What drugs cause involuntary muscle movement?

Stimulant drugs (e.g., amphetamine, methylphenidate, and pemoline) have been known to produce a variety of movement disorders such as dyskinesias, dystonia, stereotypic behavior, and tics. The most common movement disorders associated with TCAs are myoclonus and tremor.

Why do arms pulsate?

Changes in your heart rate or rhythm, a weak pulse, or a hard blood vessel may be caused by heart disease or another problem. As your heart pumps blood through your body, you can feel a pulsing in some of the blood vessels close to the skin’s surface, such as in your wrist, neck, or upper arm.
