Patient's question:
Hello, my daughter is 10 years old this year. When she gets nervous, her hands will twitch, and her limbs will become stiff. She feels tightness in her chest and has difficulty breathing. Is this the right department to see? Do you work normally during the Spring Festival?Doctor's answer:
Muscle cramps are a colloquial term for convulsions, which are a manifestation of temporary dysfunction in brain function. The movement of human muscle is controlled by the brain. When the brain cells responsible for muscle movement become temporarily overexcited, uncontrollable muscle movement occurs, which can be limited to a group of muscles or one side of the body, or affect the entire body, known as cramps.### I. Causes of Muscle Cramps
High fever, epilepsy, tetanus, rabies, calcium deficiency, and other conditions can cause cramps. These are systemic issues. There are also localized causes, such as calf muscle spasms (commonly referred to as "calf muscles"), which are often triggered by sudden exercise, work fatigue, or severe twists in the lower legs. They frequently occur when lying down or sleeping.
### II. Clinical Manifestations:
1. Generalized tonic convulsions: All muscles become rigid, with intermittent contractions, presenting as opisthotonos (head tilted backward, body arched backward like a bow), upward rolling of the eyes or fixed gaze, and unclear consciousness.
Recommendations:
2. Localized convulsions: Only localized muscle contractions occur, such as movement of one limb, facial muscle twitching, finger or toe twitching, eye movement, nystagmus, blinking, or fixed gaze. Most cases involve unclear consciousness. The duration of these convulsions can range from a few seconds to several minutes. Severe cases may last for several minutes or recur repeatedly. Convulsions lasting more than 30 minutes are referred to as status epilepticus.
