Characteristically, a cramp is painful, often severely so. Usually, the sufferer must stop whatever activity is under way and seek relief from the cramp; the person is unable to use the affected muscle while it is cramping. Severe cramps may be associated with soreness and swelling, which can occasionally persist up to several days after the cramp has subsided. At the time of cramping, the knotted muscle will bulge, feel very firm, and may be tender.
There are no special tests for cramps. Nevertheless, the diagnosis of muscle cramps is relatively easy. Most people know what cramps are and when they have one. If present during a cramp, the doctor, or any other bystander, can feel the tense, firm bulge of the cramped muscle.
