A muscle spasm or cramp is an involuntary contraction; tension is often used more broadly for a tight feeling or sustained effort. Describe timing and movement rather than assuming the two terms identify the same condition.

A worked situation: Shoulder tightness

Fictional example. A reader reports ongoing shoulder tightness and a sudden painful leg contraction lasting briefly. Separate entries give a clinician a clearer history than calling everything stress tension.

Describe sustained and sudden experiences separately

If you noticed an ongoing tight feeling and a separate abrupt contraction, record them as two observations with their own timing. The cramp source describes an involuntary contraction; it does not establish the cause of every sensation called tension. Neither the table nor an optional movement can diagnose the distinction or clear a concerning symptom.
