Muscle cramp
Muscle cramps can be defined as an involuntary temporary strong muscle contraction or overshortening which may cause severe aches and pains. Usually the onset is sudden while the cramp resolves spontaneously in a few seconds to minutes.
In the context of substance usage, certain compounds induce muscle cramps which, depending on the drug, can range from mild to extremely uncomfortable in their intensity and are rare to frequent in their consistency.
