What might be causing your left hand and fingers to twitch?

* Peripheral neuropathy: This condition occurs when the nerves that lead from the brain and spinal cord to the arms and legs are damaged. Peripheral neuropathy can cause tingling, numbness, weakness, and twitching in the hands and fingers.

* Herniated cervical disc: A herniated cervical disc occurs when the soft, cushioning material inside the discs between the vertebrae in your neck leaks out and presses on the nerves. This can cause pain, numbness, weakness, and twitching in the arm and hand on the affected side.

* Carpal tunnel syndrome: Carpal tunnel syndrome occurs when the median nerve, which runs from the forearm to the hand, is compressed in the carpal tunnel, a narrow passageway in the wrist. This can cause pain, numbness, tingling, and weakness in the hand, wrist, and forearm.

* Muscle spasms: Muscle spasms are involuntary contractions of the muscles. They can be caused by a variety of factors, including dehydration, electrolyte imbalances, and certain medications.

* Restless legs syndrome: Restless legs syndrome is a condition that causes an irresistible urge to move the legs. It is often accompanied by twitching in the legs and feet.

* Anxiety: Anxiety can cause a variety of physical symptoms, including twitching in the hands and fingers.

* Caffeine: Caffeine can increase the activity of the nervous system, which can lead to twitching in the hands and fingers.

* Medications: Certain medications, such as stimulants and corticosteroids, can cause twitching as a side effect.

If you are experiencing twitching in your left hand and fingers, it is important to see a doctor to determine the cause.
