Causes and symptoms of limb convulsions

Clinically, there are many reasons that cause people to have limb convulsions, and people should know more about the causes of limb convulsions in their daily lives. The following article will introduce the causes and politics of limb convulsions to everyone.

Causes of limb convulsions:

High fever, epilepsy, tetanus, rabies, calcium deficiency, etc. can all cause cramps, which are systemic. There are also local ones such as gastrocnemius muscle (commonly known as calf) cramps, which are often caused by rapid exercise, work fatigue, or severe twisting of the thigh, and often occur when lying down or sleeping.

Symptoms of limb twitching:

1. Generalized tonic convulsion: The muscles of the whole body are rigid, twitching in waves, showing opisthotonos (the head is tilted back and the whole body is bent backward in a bow shape), the eyes are rolled up or staring, and the person is unconscious.

2. Localized convulsions: only local muscle twitching, such as twitching of only one side of the limb, or twitching of facial muscles, or twitching of fingers and toes, or eyeball movement, nystagmus, blinking, staring, etc. Most of them are unconscious. The above convulsions can last for a few seconds or minutes, and in severe cases, they can last for several minutes or recur. If the convulsion lasts for more than 30 minutes, it is called a continuous state of convulsion.

3. Fever convulsions: mainly seen in children aged 6 months to 4 years old who have convulsions during high fever. Fever convulsions are short-lived, and consciousness recovers quickly after convulsions. They often occur in the early stage of fever. In a fever, there is often only one convulsion. Brain diseases and other serious diseases can be ruled out, and the electroencephalogram is normal one week after the fever subsides.
