Panic after lumbar sprain may be caused by the body’s stress response leading to arrhythmia, or endocrine disorders leading to panic. 1. Stress response: after a lumbar sprain, intense pain triggers sympathetic nerve excitation, resulting in an instantaneous increase in heart rate, peripheral vasoconstriction, resulting in increased blood pressure, which can lead to increased work of the heart and increased cardiac load, thus triggering arrhythmia and panic symptoms. Need to immediately seek medical attention, first of all, the lumbar sprain treatment, panic can generally be relieved. 2. Endocrine disorders: lumbar sprain after intense pain stimulates the body adrenaline, glucocorticoid hormone levels rise, triggering a decrease in renal blood perfusion, blood pressure rises, suffering from cardiac underlying diseases heart load increases, panic and dizziness and other manifestations. If necessary, you need to go to the cardiology department. Lumbar sprains require urgent treatment, strictly prohibit unnecessary activities, and actively seek medical treatment for lumbar sprains, and panic can be relieved on its own. A small number of patients with hidden heart disease, can not be relieved actively contact the Department of Cardiology for consultation, diagnosis and clear treatment of the cause.
