What does convulsing mean?
To be convulsing is to undergo violent, involuntary shaking or jerking movements — most commonly the muscular contractions of a medical seizure such as those caused by epilepsy, fever, or poisoning, but also, by extension, any state of violent agitation. A person might be found convulsing after a head injury, while a crowd can be described as convulsing with laughter when gripped by uncontrollable mirth. The word derives from Latin roots meaning 'to pull apart' or 'shake violently', which explains its forceful, dramatic character. Because it strongly signals loss of bodily control and distress, it is used sparingly and seriously in medical writing, yet it appears freely in literary and journalistic prose where writers want to convey extreme physical or emotional upheaval. It is the progressive form of the verb 'convulse', typically describing the action as it happens.

Etymology of convulsing
'Convulse' derives from the Latin verb 'convellere', meaning 'to pull violently apart' or 'to shake', formed from 'com-' (together) and 'vellere' (to pluck or tear). The English word was borrowed in the early modern period, appearing in medical and scientific writing by the seventeenth century to describe seizures and spasms. Its relatives include 'convulsion' (the noun), 'convulsive' (the adjective), and the rarer 'revulse', all built on the same tearing-or-shaking root.
How convulsing is actually used
Primarily used in medical and emergency contexts for literal seizures; figurative use ('convulsing with laughter') is vivid but common. Carries a strong connotation of violence and loss of control, so it is intense rather than neutral in tone.
