If a calf cramp occurs while driving, you should change the position of the leg and stretch the calf in a timely manner while ensuring that the vehicle is stopped.
The way of stretching is to straighten the lower limbs, the trunk forward bending, with both hands to trigger the forefoot, slowly and continuously to the trunk side of the pull, until the spasm is relieved.
After the spasm is relieved, you should avoid causing local muscle spasm again, keep the temperature in the car suitable, or pay attention to the warmth of the legs; reduce the heavy weight pressure on the legs and insteps.
Leg cramps are mostly caused by calcium deficiency, cold and local neurovascular compression. Normally, you can take calcium supplement, get more sunshine, sit and sleep in a way that avoids pressure on the nerves and blood vessels, and you can also do hot compresses and massages on the local muscles to strengthen the local blood circulation.
If there are frequent cramps and it is difficult to relieve, you should go to the hospital in time to find out the cause of the symptoms, and actively cooperate with the treatment.
