Muscle strain is caused by the sudden rapid running of calf muscles in a static state, and the muscles are suddenly pulled by tendons, and the muscle fibers with little damage are broken and damaged, causing pain. Then there is the sudden contraction of muscles under tension. Although running stopped, the muscles were still in a state of tension and did not relax, which also caused tension and pain.
If it's not a real strain, it will usually be fine in a few days. If you are really tired, you should stop activities and have a rest. In order to promote blood circulation, you can use a warm towel for hot compress or do a relaxing massage. Be sure to take part in sports activities. You should exercise your ankles, arms, waist and neck first. If you are well prepared, you will avoid getting hurt.
After running strain, you should pay attention to rest, avoid cold and keep warm, exercise properly, massage and compress locally, and take Huoxue Zhitong capsule for treatment.
