muscle spasm
Sudden painful twitch
A muscle spasm is an involuntary contraction of a muscle that occurs suddenly and often painfully.
Spasms can range from brief twitches to sustained cramps that lock the muscle in a contracted state.
They commonly result from overexertion, dehydration, or electrolyte imbalances, though they can also signal underlying conditions.
I woke up with a muscle spasm in my calf that wouldn't release.
