The lymbic system of the brain can cause these problems.
epinephrine and norepinephrine stimulate the sympathetic nervous system
Thermoreceptors in the nerve cells of the mouth respond to temperature of objects. When these receptors are activated, ion channels are opened and action potentials are sent to the central nervous system. Cool objects/food activates these thermoreceptors. However, if something that is too cold enters the mouth, nociceptors will be activated. These receptors register pain and inform the central nervous system that the object is harmful.
