Tight


If a pulse is Tight pathologically, however, which is less common, it indicates stagnation.  Cold is the chief cause of stagnation manifesting as Tightness in the pulse.  Damp causes resistance too, but a Damp, Tight pulse is called Slippery.  Tight pulses can be Slow, reflecting the Cold, or Rapid, indicating the beginning of the generation of Heat in response to Cold.  Since Cold has a constrictive quality, a Tight pulse can indicate lateral, costal and flank pain.  Tightness can also indicate the consumption of Yang, which results in Cold. True stagnation is present in a pulse that does not give way.  If a Tight quality is found but gives way when you push beyond it, it is technically not a Tight pulse, but Leathery, Firm, or Hidden.  A pulse could be Tight perhaps on the surface level and then Hidden on the deep level.  That would technically not be a pulse of true stagnation.

Psychologically a Tight pulse can mean resistance to change, physical hesitation, sluggishness or fatigue.
