Most of the causes of muscle spasms and convulsions are due to acute external force on the local muscle tissue of the patient. Long-term chronic strain and strain in the local area leads to local muscle damage and lactic acid accumulation in the muscles, as well as muscle nutrient metabolism disorders, and the patient may have muscle spasms, cramps and pain. In addition, the patient’s local muscle tissues, which have been exposed to cold for a long period of time, may also produce this phenomenon when the local qi and blood do not run smoothly, and there is qi stagnation and blood stasis, and the meridians are blocked. In clinical practice, when this phenomenon occurs, the patient should be instructed to pay attention to local warmth and not to catch cold. Local hot compress treatment, local herbal fumigation using orthopedic wash, or with low and medium frequency electrotherapy, microwave instrument treatment, bioelectric therapy, etc. can be carried out. Accelerate the local blood circulation and promote metabolism, which can reduce or alleviate this phenomenon.
