In brief: Cramps hurt

A cramped muscle is a painful, tight and involuntary contraction of most of its fibers (think charlie horse).
A twitching muscle is when a few of its fibers spontaneously rapidly contract; release and contract again, but painlessly.

In brief: Cramp vrs others

Muscle twitching may be fasciculation or may be a tic.
Cramps (legs) are less specific. Most of the time there is no cause found for cramps but in pts. Taking diuretics one possibility is low potassium, low calcium, or low magnesium. Calcified arteries, poor conditioning of the muscles, bad positions may contribute to experience leg cramps. Tip-toe exercises, tonic water, magnesium help.
