two types of physiological problem

imagination of event and then forget about present discomfort, the physiological reaction and get stuck with thinking about the event and assoicate the discomfort with it. keep looking for answers in the event and forget to take care of your present body discomfort.

2. when you waiting for an outcome or you anticipate an outcome , you deliberate create a discomfort physiologically if you do not know the answer but is kept waiting. you assoicate the process of being in the unknown period as painful and scary period and this is being done by unknowingly creating a physioloical discomfort to validate that this process is indeed painful one.

ex. in extreme cases, like having ahand being chopped off. you feeling numb but with clear mind. you dunno whether you are going to die or not. the period of not knowing if you will die causes you to fear by physiologically changing your internal muscles to create the tension of discomfort. you will not know that by relaxing this muscles you will relieve the stress, so instead you keep feeling the tension of discomfort and assoicate it fact that you are afraid of the unknown. "will i die?" will be the focus for as long as the situation remains in the unknown, along with the removable pain.
