A client comes to the clinic who complains of pain in the calf of his leg. The doctor tells him that he is having a severe muscle spasm in the leg from jogging. The client asks the nurse why the muscle spasm hurts to such a degree
The nurse tells the client which of the following? 1. The pain in the leg is stimulated by the trauma of jogging.
2. The pain is due to swelling from the trauma of jogging.
3. The pain is due to excessive heat in the muscle generated by exercise.
4. The pain is due to release of chemicals due to mechanical stimulation from jogging.
4
Rationale: Muscle spasm pain is caused by the release of chemicals secondary to mechanical stimulation. Jogging does not cause swelling, trauma, or excessive heat. However, the client could have been jogging in extreme heat, or could have twisted the muscle to cause the release of the chemicals into the muscle. The chemical stimulation causes spasm in the muscle, which is very painful.
