There are many reasons for staying up late with chest pain, the most common cause is neuralgia, especially pain in the form of pins and needles, a few seconds of this pain each time, is often neuralgia. Neuralgia is not caused by heart reasons at all, but is generally due to poor sleep or mental and psychological stress, resulting in a temporary abnormal phenomenon of nerve function. This pain lasts for a short time, usually a few seconds, and is not harmful to the body and does not require any interventional treatment. However, if a patient with coronary heart disease has chest pain after staying up late, extra caution is needed.
