Which is a sign of a seizure?

A sign of a seizure is muscle rigidity. During a seizure, particularly in generalized tonic-clonic seizures, the body can experience sudden and intense muscle contractions leading to rigidity. This is often a characteristic feature, especially in the tonic phase of the seizure where the body stiffens and becomes rigid.

Loss of consciousness is also associated with seizures, but it often manifests alongside other signs rather than being solely indicative of a seizure. Similarly, chest pressure and cold, clammy skin can suggest a range of medical conditions or situations but are not specific indicators of seizures. Understanding these signs can help in recognizing seizures and ensuring prompt and appropriate responses.
