That sudden little muscle jump can be surprising if you’ve never experienced dry needling before.
It’s often referred to as a local twitch response and happens when the muscle reacts to stimulation from the needle.
The sensation is usually very quick and may feel like a brief cramp or flicker in the muscle.
Not every treatment produces a dramatic twitch, and that’s completely fine. My focus is always on how your body responds rather than chasing a particular sensation.
