A: What you describe sounds like carpal spasm. Spasms, or cramps, are involuntary muscle contractions. The most common causes of spasms are overused muscles (in the hands that might be due to writing or typing) and dehydration. Other causes of muscle cramping include low levels of calcium and magnesium.
Then, what causes Carpopedal spasms in hyperventilation?
Carpopedal spasm occurs when acute hypocarbia causes reduced ionized calcium and phosphate levels, resulting in involuntary contraction of the feet or (more commonly) the hands (see the image below). Chvostek or Trousseau signs may be positive because of hyperventilation-induced hypocalcemia.
What causes muscle spasms?
Spasms of skeletal muscles are most common and are often due to overuse and muscle fatigue, dehydration, and electrolyte abnormalities. The spasm occurs abruptly, is painful, and is usually short-lived. It may be relieved by gently stretching the muscle.
What causes spasms in your hands and feet?
Cramps or spasms in the muscles often have no clear cause. Possible causes of hand or foot spasms include: Abnormal levels of electrolytes, or minerals, in the body. Brain disorders, such as Parkinson disease, multiple sclerosis, dystonia, and Huntington disease.
