If the pressure point strike includes pain, it includes tissue damage.If it is painless, yet, somehow, still effective? Then, it's arguable that it is 'unhealable.'
Pressure: The baroreceptor in the carotid artery is pressure-sensitive, allowing the body to control the bloodflow into the brain. Pressure against this region will 'trick' the body into thinking that blood pressure is too high, and thus will constrict and lower blood pressure - which can cause blackout. Striking veins and arteries can also cause them to shut or tear, both of which will definitely cause black-out and possible death if not treated immediately.
There are lots of techniques that can be activate with minimal damage to the artery, nerve etc. And besides, you can feel pain without getting physhicalle damaged. Pain receptors can be fooled rather easily.
Pressure point attacks work on many areas, sensitive spots, nerve clusters, veins, ateries.
To break an attacker's grip, apply strong pressure to the cuticle of his thumbnail. Your attacker will find it painful, but you won't cause any physical damage.
Pretty much tells you that you can cause pain without physical damage.
