Mild shortness of breath can be cured in a few minutes, while serious shortness of breath should be further treated in hospital. The reason of having a stoke is often due to exerting too much force, which is more than the patient can bear to do the exercise, mostly seen in weight lifting, long jump, high climbing, running, etc.. The time it takes for a stoke to heal itself is related to the severity of the stoke. If the stoke is mild, the stoke will usually heal in a few minutes or on the same day. If the symptoms are serious, you can use your hands to gently rub the stoke, and if it still can’t be cured, it is recommended that further treatment be given in the hospital. To prevent gas, you should focus on warming up before exercise and not exerting yourself too hard. Avoiding trauma is also a good way to prevent gas.
